I've remembered a good one.
In the 80s some of the trains from S Wales to London were the old corridor-and-compartment type.
I shared a compartment from Newport to Paddington with George Melly. He slept most of the way and snored incredibly loudly.
We did not speak to each other.
I wonder if that was after I saw him performing at Harry Ramsdens (now a 'Spoons) in Cardiff Bay.
