In answer to Tyke's question, the person next to Roger on my picture isn't Mark Knopfler - his name is Mark Peers. It was an informal jug band jam session that Roger and Nick joined in with, and Mark Peers is on washboard, his brother Jim on jug, Johnny Wall on trumpet mouthpiece / paraffin funnel, and me on kazoo / metal funnel. There may well have been other musicians out of shot - I can't remember, and it was very crowded as you can see from the pictures.
