Just read a hilarious article in the Sunday Times, Just Jack on Train in Vain by the Clash, which he say he played 50 times in a row and then states:

"I love Joe Strummer's vocal, it has the usual gnarly roughness, but is tempered with a more tuneful, almost yearning quality. The lyrics speak of a great injustice done to Strummer by a woman."

Train in Vain was sung by Mick Jones and mostly written by him too and Just Jack you've just made an idiot of yourself in print.
