The native son of Fargo, North Dakota was a natural playing the piano, harpsichord and the Vox.
Perhaps the greatest example of his work came from his 1962 Dot Records album Frank Scott Plays Harpsichord
Each and every of the tracks is a instrumental gem, like Boogie Woogie, Yankee Doodle Rag and Woodchopper's Ball just to name a few. You can find the album at a vintage record shop near you or search on ebay or any fine reputable online auction site.
In the meantime, here's two of the tracks from the album you can have a sample with.
