Fans queuing to get into the Black Rebel Motorcycle Club gig at London's Electric Ballroom last night were treated to an impromptu acoustic performance from singer Robert Turner.

Doors to the gig didn't open until 9pm as some of the band's equipment apparently failed to make it to the venue on time.

The hundreds of fans standing on the Camden High Street to get into the gig cheered when Robert Turner suddenly appeared outside the venue with an acoustic guitar.

He then treated the bewildered fans to a Black Rebel medley after apologising for the delayed show.
