Rod Stewart, Michael Caine and Joan Collins, 86 celebrate Tramp nightclub's ...

From The Beatles to George Best to Mick Jagger, the biggest names have descended on Tramp nightclub since its opening in the swinging sixties. 

And some of the club's most loyal customers returned to the scene of many a raucous evening on Thursday night, as Rod Stewart, 74, Joan Collins, 86, and Michael Caine, 86, led the stars for the club's 50th anniversary in Mayfair. 

Rod, who was joined by his wife Penny, 48, was caught flashing his bottom at the camera as they entered the building shortly before he was followed by the stars - who undoubtedly have boundless tales from the inside of the club, which soared to prominence with its boasts of treating 'everyone like a VIP'.

Tramp has long been a hotbed for superstars, with the current general manager of the venue, David Fleming, detailing the appeal of the hot-spot as he said: 'What happens in Tramp, stays in Tramp'. Michael also said in the past: 'I used to live in Tramp. I was in there every night – givin’ it some of that!'

After 17 years of working in the club, David, 55, spoke to Luxury Life about the behaviour in the club, saying: 'People are actually surprisingly well behaved in here. Stars are definitely more discreet now and also look after themselves more, so there isn’t so much of the excess that took place in the 1970s...

'But the thing about Tramp is that, whether you’re a star or not, everybody who is a member is aware that it’s a huge privilege to be part of it. And so people do behave. I’ve only had to ban two people in the past five years.'

Throwing her support behind her husband, Penny showed off her supermodel figure in a back and grey striped minidress, which she complemented with black court shoes and a velvet YSL clutch bag.

Joan, 86, meanwhile cut a glamorous figure in a black bardot dress as she headed to the bash with her smartly-dressed husband Percy Gibson. 

The Hollywood legend had her wedding reception at the club, and was one of many;  Peter Sellers, Liza Minnelli and Ringo Starr also partied until the early hours after tying the knot.
