I learned this from Chirps Smith. He learned it as part of the tune-collecting project that eventually spawned "Dear Old Illinois." He started adding the "Illinois" to signify that he wasn't just playing regular Ricketts Hornpipe wrong.
Mark asked me to help him out on this project of music mentioned in, or inspired by, the writings of Edgar Lee Masters. With Sharon Graf, we are providing music for a new play titled My Heart's Home. Erich Schroeder
