Ricky Gervais performed as David Brent with his band Foregone Conclusion at the world premiere of his new movie 'David Brent: Life On The Road' on Wednesday night (10.08.16).

London's Leicester Square played host to the comedy band - which includes Andy Burrows on drums - that features in the highly anticipated 'mockumentary' movie with the 55-year-old star stepping on stage as his alter ego from TV sitcom 'The Office'.

Brent and his bandmates performed a host of tracks from the film including 'Life on the Road', 'Slough' and the hilarious 'Equality Street' - for which they were joined by Doc Brown rapping politically correct lyrics as his character Dom Johnson.

The joke band received a rapturous response from the hoard of fans who had gathered to witness the premiere and Gervais as Brent rewarded them by firing T-shirts into the crowds.

Foregone Conclusion closed their set with 'Free Love Freeway', which first featured in the 2001 episode of 'The Office' entitled 'Training' and fans shouted out jokes from the show during the performance prompting Gervais to plead with them ''please don't'' as he struggled to stop himself from bursting out laughing.

Speaking on the red carpet before the gig, Burrows - who is currently touring with Tom Odell - admitted it had been ''incredible'' working on the film and described Gervais as Brent as the ''greatest frontman of all time''.

Afterwards, Gervais - famous for his outrageous hosting of the Golden Globes - walked the red carpet to meet fans and happily signed autographs and posed for countless selfies, including several photos with guys wearing Brent masks.
