There is literally only one thing on our minds today and there's really no getting used to it. A musical hero is no longer with us, and with his passing pour in thousands of tributes from his devoted fans, friends and former collaborators. But which unforgettable David Bowie unions are still putting a smile on our faces today?

David BowieDavid Bowie leaves behind a lasting legacy

For many of the performances, Bowie was joined by his devoted session guitarist Mick Ronson, and, of course, this isn't the full list of Bowie collaborations. There are such gems as Christmas classic 'Peace on Earth/Little Drummer Boy' with Bing Crosby, 'The Buddha of Suburbia' with Lenny Kravitz and 'Province' with TV on the Radio, but here are 13 of our all-time favourites.

1. With Arcade Fire - Wake Up: Bowie teamed up with this multi-instrumentalist Canadian band at the Fashion Rocks charity fundraiser in 2005, dueting an emotional 'Wake Up' from their debut album 'Funeral'. Their partnership didn't end there, though, and Bowie later returned as a backing vocalist on the title track of their 2013 hugely acclaimed number one album 'Reflektor'.

2. With David Gilmour - Comfortably Numb: While we're on the subject of emotional music, the Pink Floyd guitarist performed a cover of the band's 1980 single 'Comfortably Numb' alongside Bowie during his 'Remember That Night' tour at the Royal Albert Hall in 2007. Even before that, Bowie unveiled his own cover of 'Arnold Layne', following the death of Syd Barrett, as part of a tribute single by Gilmour recorded live at the Albert Hall the previous year.

3. With Lou Reed - Queen Bitch: Reed and Bowie have had quite a longstanding relationship. The latter helped Reed find a wider UK audience, co-producing his 1972 album 'Transformer' with his trusty guitarist Mick Ronson. Thus, it was no surprise that he made an appearance at his 50th birthday celebration in Madison Square Garden, New York, in an event entitled 'David Bowie and Friends' during which the two performed 'Queen Bitch'; a song released by Bowie in 1971 in tribute to Reed and Velvet Underground.

4. With Billy Corgan - All The Young Dudes: That same birthday also saw Bowie team up with Billy Corgan from The Smashing Pumpkins, singing 'All The Young Dudes' which the former originally wrote for Mott the Hoople to persuade them to stay together. Corgan later admitted that Bowie's birthday gig was his favourite memory of the singer.

5. With Robert Smith - Quicksand: It was only appropriate for The Cure's Robert Smith to join Bowie on a rendition of one of his darkest numbers, 'Quicksand' from 1971's 'Hunky Dory'. Two of the most distinguishable voices in the history of music performing in perfect synchronicity at Madison Square Garden. That was one lucky audience.

6. With Foo Fighters - Hallo Spaceboy: It was originally a huge electronic number featuring Pet Shop Boys (remember the 1996 Brit Awards?), but Bowie swapped synth for strings when he invited Dave Grohl's band Foo Fighters to duet on 'Hallo Spaceboy'. What can we say? No-one ever thought it would work as a solid grunge number but it really, really did.

7. With Trent Reznor - I'm Afraid of Americans: Bowie liked singing about America - 'Young Americans', 'Alabama Song', 'This Is Not America' - but by far the best song is 1997's 'I'm Afraid of Americans', produced by Nine Inch Nails. The video for the song actually features a scary-looking Trent Reznor as Jonny, rather hilariously chasing Bowie through the streets and shooting at him with an imaginary assault rifle. Nine Inch Nails have frequently covered the track on tour, and Bowie also did a version with Sonic Youth for his 50th birthday. His previous work with industrial rockers includes their collaborative 'Outside Tour' in 1995, where they performed 'Hurt' together.

8. With Iggy Pop - The Passenger: Iggy Pop was another huge friend and partner of Bowie's. Not only did the latter take him with him on his Station to Station tour in 1976, but he also co-wrote and produced his first two solo albums 'The Idiot' and 'Lust for Life' with his backing vocals featuring on such tracks as 'The Passenger'. You may also know of their collaborative track 'China Girl' which originally featured on 'The Idiot' before getting a re-release on Bowie's 'Let's Dance' album.

9. With Queen and Annie Lennox - Under Pressure: Following the death of Queen legend Freddie Mercury, Bowie was among the many artists who paid tribute to him in a concert at Wembley Stadium. He had co-written Queen's 1981 number one 'Under Pressure', and subsequently performed the track alongside Annie Lennox at the tribute concert.

10. With Placebo - 20th Century Boy: There's too many great stories to tell of Bowie's friendship with T.Rex's Marc Bolan. Bolan's appearance on Bowie's 'The Prettiest Star', that episode of 'Marc' where Bolan fell off the stage during their duet, and so it was no surprise that he was more than happy to get on board with Placebo for their live rendition of '20th Century Boy' at the 1999 Brit Awards. He also collaborated with the London alt rockers on their single 'Without You I'm Nothing'.

11. With Mick Jagger - Dancing in the Street: It's difficult to think of anything more fabulously camp than the video for Bowie and Mick Jagger's cover of Martha and the Vandellas' 'Dancing In The Street'. Indeed, it was dubbed 'the gayest music video of all time' in an episode of 'Family Guy'; affectionately enough, though, and consequently played in full. A number one in 1985, it was recorded with limited time for Live Aid.

12. With Tina Turner - Tonight: As well as getting her signed to Capitol Records, Bowie had Tina Turner team up alongside him for the title track of his 1984 album 'Tonight'. The pair even shared the stage for the song during her Private Dancer Tour, as well as doing a collaborative rendition of 'Let's Dance'.

13. With the cast of 'Labyrinth' - Magic Dance: Just for fun, we can't leave a list like this without a mention of his epic performance in Jim Henson's 1986 'Labyrinth'. He performs alongside the goblin puppets, and it certainly cheered up baby Toby!
