"Dora Dean" is from the repertoire of blind professional fiddler Ed Haley. He performed widely in Kentucky, West Virginia, Virginia and Ohio. Haley played over WLW in Cincinnati and made occasional studio recordings for friends. He made many recordings of his playing for the family on a Wilcox-Gay disc-cutting machine brought home from the service by his stepson Ralph.
"Dora Dean" is in F, an uncommon key for old-time players, but it is really a pretty easy tune with a good sound. It is actually the same melody as "I Don't Love Nobody". The B part in the minor key gives it a funky, ragtime feel.
This is one of the post-ragtime "rags" that fiddlers and mandolin players developed in the early 20th century using the syncopated rhythms of the ragtime tradition.
The banjo tab is from the playing of Adam Hurt.

I learned this from the playing of Adam Hurt (on fiddle, not banjo) on his Artifacts CD.
