An interesting (if primitive)example of a tune on the very famous chord sequence
I IV I V I !V !-V I. Often referred to as the "Gregory Walker" sequence from its first(??) known 16th century example. Members of the family include Jesse James, Swanee River, Dvorak's Humoresque etc etc. Come to think of it, I've never actually heard Gregory Walker, just read about it.
   Just waffling here, covering up the fact that I can't identify the tune.
