This was the very first "tape music" piece I ever put together (1973), utilizing the only tools available to me at the time, a cassette deck and my record collection.

Although I cleaned up the transitions a bit for this 1999 release, the track is exactly as it appeared on my first tape "Early Cassetto" (1973), which became part of "Floyd Cramer's Hall of Gold" (1975). It was released again 40 years later on VOD's "Tape Recordings 1974-1979" (2015).
