Let me tell you VT, that was a lot of money in those days. I booked Johhny Silvo for £15, Derek Brimstone for £10, Stefan Grossman for £15, and Jeremy Taylor for £15, all in 1968. By which time, I think Paul had gone back to the states. I remember seeing him fairly often in the early days of my involvement in south of England folk clubs.
Alan must be almost as old as me ;)
