Hi Peter you're exactly right saying Richard S first, probably right with the time period as well. Can't believe you'd never heard the flip, he was playing them both at the same time. Both sides were covered as Spyder Turner and The Webs.
Dave Raistrick found the second copy probably around 1981/82. He put it up for auction on his list still covered up. I had a go at getting it but it went quite high (for the time). Dave Withers won it I think at around £160. I did get one a couple of years later, not too sure where that went, might have been to Jimmy W.
