And here's a piece of trivia. My mother once told me that when she was a child that if a singer forgot words someone would be sure to remark "He's got a hole in his ballad". The reference was to a broadside or songsheet bought at a market or fair. It would be folded twice and eventually wear and tear would make a hole in the middle of the sheet rendering the text unreadable. In Joyce's "Finnegans Wake", among the presents that HCE gives to Anna Livia Plurabelle is a hole in a ballad. This is my contribution to Joyce scholarship.
