Tickets for Ricky Gervais's first musical live shows as his Office character David Brent have sold out in under 60 seconds.

Gervais is playing two warm-up shows for the 'David Brent & Foregone Conclusion Live - A Work In Progress' tour at London's Bloomsbury Theatre later this month, but lots of fans were left disappointed as tickets were quickly snapped up for the gigs,

OK, so apparently, the Brent tickets sold out in under a minute. How is that even possible? Sorry. — Ricky Gervais (@rickygervais) October 1, 2013

Gervais apologised to fans for the limited tickets, but promised that he would be offering some seats as competition prizes.

He also urged his Twitter followers not to purchase tickets from touts, describing the prices as "f**king disgusting".

The comedian revisited David Brent in a Comic Relief sketch earlier this year and followed it up by launching a 'Learn Guitar With David Brent' series on YouTube.

Gervais is expected to perform David Brent tracks such as 'Freelove Freeway', 'Equality Street', 'Spaceman Came Down', 'Slough', 'Life on The Road' and 'Ain't No Trouble' at the shows.

A full UK David Brent tour is expected to be announced soon.
