The URL given by Jim Dixon (05 Oct 10) still works, and in the Introduction you may find mentioned the titles of all the tunes stolen for the songs in the opera. So, if you are an opera buff, you should be able to supply them. No tune, however, is mentioned or given for the "local ballad" that started it all. Josh White's tune does fit it.

It strikes me that Charlie's Kitchen in Harvard Square would make an excellent venue for a performance. Perhaps the establishment could even make fish balls a monthly special, with the price scaled up according to inflation.
