WEll, Jerry, that's a fine thought-provoking idea. Off hand, I seem to have kept most of my forty year old repertoire in circulation, with a few exceptions. I used to sing Sidney Carter's "Down Below" alot, but I n o longer move in circles where it would be though funny. I see you mention the Escpe of John Webb: that, and the MTA songs, are things from the Kingston Trio/Limeliters that I have never felt likere-visiting. Maybe I will now you've raised the subject: I think the Pogues or somebody had a go at the MTA song, didnt they?
   The songs I used to love, but never go near any more, are the rugby songs, which seemed very suitable in groups of all male 18-year old college boys. But I think they might cause raised eyebrows if I slipped one into the set at a folk festival.
    But generally speaking(because I'm very lazy about learmning new songs) I find all my early repertoire(virtually all skiffle) is still quite in use.
   If I find a suitable occasion to revisit "The Engineer's Wheel", "The Mayor of Bayswater", or "Dinah, Dinah, Show us your Leg", I will report back!
