At Sidmouth a few years back we were sitting on the promenade just practising, when a bloke came up and asked if he could borrow the guitar to do a song - I duly obliged and he did a very good version of "Me and Bobby McGhee" - he then said "Thanks, I'd better get back to work now", and ran to catch up with his team on the dustcart, from which he'd taken time out to do the song.
