Entertaining the crowds

These young musicians known as Riverside Jazz were preparing to represent the Harrogate International Youth Festival this afternoon in the centre of town. They were there to welcome the BBC local Yorkshire News team Harry Gration & Paul Hudson as they finish today's stage of their sports relief 3-legged challenge.
(I didn't wait for the two local 'celebrities' to appear as they were not due for another 30 minutes or so.)
These two chaps were producing some rather funky "riffs" (I think that's the word) on their electric guitars.
