Busking undercover!

When wandering around Cambridge, we came across this gentleman (I think!) plucking away on the guitar, whilst ensconced in a rubbish bin, it can't have been very comfortable surely. I decided not to proffer an opinion or indeed a few pence, but I did have some rubbish to relieve myself of and had to look for another bin!!
Some people are so irresponsible!! And no he wasn't singing 'My Old Man's a Dustman'
