Nigel, that was a heck of a lot of work. I was debating over it while you wend ahead and did it. I hope that there is interest enough among people using this site to justify your effort.

I would like to know what the "Raging Canal" song used by Twain was like. The one in the DT is modern, from the days of Lomax and the folksingers. It may yet be found in some old newspaper or broadsheet since it was popular in the mid-ninteenth century. Several songs used its melody; which also remains uncertain.
