Sir Elton John went on an expletive-filled rant at a concert on Sunday (07.06.15).

The 'Candle in the Wind' singer was performing at the Kingsholm Stadium in Gloucester, England, when he suddenly turned on the staff who were trying to calm fans at the front of the crowd, comparing the stewards to former German dictator Adolf Hitler.

He ranted: ''Lighten up you lot, it's not f**king China so p**s off! You get a f**king uniform on and you think you're Hitler ... we're not having it, p**s off!''

However, concert organisers quickly advised the mega-star the stewards were only doing what they had been told to do, leading to the 68-year-old musician to retract his tirade.

Wearing a sparkling red suit and matching glasses, he singled out one staff member named Maria who was marshalling at the front, to apologise to, inviting her on stage for a hug.

He said: ''I do apologise, whoever told the stewards to do that, it's their f**king fault and not hers and I apologise profusely. If people want to wave their arms in the air, let them ... I apologise for my outburst.

''No-one should ever talk to a lady like that.''

The exchange didn't seem to dampen the night as fans took to Twitter to praise the 'Rocket Man' hitmaker for an amazing show.

One user gushed: ''Great night at #kingsholm watching @eltonjohndotcom in concert. Great weather and really glad I won tickets. Awesome (sic).''

Sir Elton John is booked for seven more dates across the UK on his 'Elton John and his Band' tour.
