Very fond of that one myself. I remember requesting it at a folk club in Leeds back in 1983 - Richard fixed me with a hard stare and said, "Blimey. You're a simple soul, aren't you?". But he sang the song and, taking pity on a penniless student, gave me a copy of his cricket book 'Run Out In The Country" after the gig. Top man.
