A Spanish Elvis, pop singer/songwriters and operatic harmonies have been bounding around Canary Wharf Tube station as part of London Underground’s search for new musical talent.

Sought-after licences for the London Underground network and TfL’s broader estate are up for grabs through Busk In London auditions, which are running until mid-August (dates have been added to fit in with the expected Tube strike on August 5)

This is the first time performers have auditioned through an X Factor-style competition, where a panel of music industry experts will choose their favourites based on originality, technique and performance.

The competition is part of the Mayor Of London’s Busk In London initiative, which was set up to support and promote busking in the capital, with locations set to be announced over the summer.

London Underground’s director of strategy and service development Gareth Powell said: “Performing on the Underground network has been a rite of passage for London musicians for generations and busking is a fantastic, tried and tested way to reach a diverse audience.”

Auditioners – who are scheduled to be playing across London until August 8 - www.buskinlondon.com for more information – will also be at The O2 on Thursday, July 30 and Monday, August 3.
