Tom Jones Goes Busking. Why? Why? Why? For Charity

The legendary Sir Tom Jones will be giving unsuspecting members of the public a rare 'treat' tomorrow when he goes busking on the streets of London.

BBC2's Culture Show are filming him as he performs three songs outside the front of the Royal Festival Hall at 3pm on Weds as part of their occasional 'British Busking Challenge', which features stars performing for charity.

Sir Tom will sing accompanied by just an acoustic guitarist - something he's not done in many years. Not even the weather can stop him - if it rains, he'll be performing in the local covered skateboarding park nearby.
