My memory's far too hazy to be of much use on this thread, but I recall singing lustily, at least some from the BBC booklet, "What's in There? (Gold and money...)," "Charlie is me Darling," "Oh No John" (not the rude verses I'm sure!) and "Bonnie Dundee."   There was also a round that our teacher would torment us with by making a randomly-selected four of us sing it "solo," called something like "Morning is Come."   That's when I first learned the art of not getting volunteered by dint of avoiding eye contact. This was all around 1960-ish or before. Thanks for making me dredge my memory banks so pleasurably!
