To Alan Whittle,yes I'm the Chucklefoot you saw at Cambridge festival back in the 70's,thanks for the compliment,TA! The marine disaster you refer to was a cruise ship,the "Achille Lauro",I was one of the performers on board,the ship caught fire in the Indian Ocean on the way to the Seychelles,and we had to abandon ship approx 50 miles off Somalia.
After being in a liferaft for about 6 hours,we were rescued by a tanker,and taken to Mombasa,the T.V. footage shows the ship coming into Mombasa with me leading the bedraggled passengers in a heartfelt version of "Show me the way to go home!!!"
