ITV interview with a man introducing himself as Banksy... in 2003

Would you forget you have interviewed Banksy??

This journalist from ITV News apparently did :) 

ITV News has uncovered what experts say could be the only televised interview with the secretive Bristol artist Banksy. The recording, from 2003, is the only-known time he has spoken on camera, and was found in the tape vaults of ITV News. But is it the elusive graffiti artist known around the world for 'Girl with the Balloon', 'The mild, mild west', and lately Stormzy's outfit at Glastonbury.
