Forgot about that one! Top hymn. The one we boys all hated was a Jesus-in-the-manger one. The chorus went "we will rock you, rock you, rock you" (I know that sounRAB like Queen), and all the girls would pretend to rock a baby as they sang it. Yuk! I'm sure one line went "darling darling little man" too, very strange, maybe it was one of these modern ones?
