Ammons was one of my earliest heroes. His "Swanee River Boogie" was one of the first records I tried to emulate in my early teens. It was a hit, and so he did a lot of these "commercial" boogie woogie things for Mercury. The story is nicely told in a 1997 bio by Christopher I. Page, published by the Northeast Ohio Jazz Society (Cleveland). Great photos, too. Butch Thompson
