I realize it has been two years since the question was asked about the tune "Dear Evalina, Sweet Evalina" but I have the answer. Actually the coincidence is astounding. A friend tonight sent me a URL that eventually led me to this web site. Following another path from the URL a few minutes earlier led me to a midi of Dear Evalina, which happened to be my father's favorite song. The only copy of the sheet music I have ever seen was in the Library of Congress in Washington.So here's the URL for the midi/lyrics to Dear Evalina, Sweet Evalina. http://www.contemplator.com/america/evelina.html
My father grew up on the prairies of Saskatchewan, born in 1909. I suspect he learned the song from a traveling minstrel show.
This is a wonderful web site. I've learned a lot tonight.
