There's an old guy with a Belfast twang who busks in the escalator well at Monument Metro Station. He raises money for the Red Cross.
Alongside hymns like 'Rock of Ages', and songs I imagine go down well at Working Mens Clubs - '(I don't wanna leave) Old Durham Town'; anything by Roy Orbison - occasionally he places a more modern song in the mix.
Today you've about got it if you can imagine Ian Paisley singing 'Blowing In The Wind' with a heavy nod to 'An English Country Garden'. I kind of think Bob Dylan would have been proud.
