When the songs were cut, most of the players on the weren't in prison for life, but for other, comparatively minor sentences. Most of the band members, in fact, were only in for a few years on a charge of Uttering and Publishing, which seems to relate to forgery or passing bad checks, with a couple notable exceptions.
Al Gliva, the songwriter, was in the joint on two occasions: he did 12 years for armed robbery, unlawful use of an automobile, and Unlawfully Driving Away an Automobile. He served time in the clink again for second degree murder, but the records are sketchy here. It looks like he was released in 1967, either on parole or at the end of his sentence.
Clyde Stanley, the man who was employed by my grandfather at his HVAC repair business after WWII, and who built a banjo and guitar for my grandfather bearing the Stanley name while in prison, did worse. He was in the can for 11 years on charges of Uttering & Publishing and Kidnapping. He was released in 1964, and came to St. Louis and found a job with Pat. Four years later, he was convicted of firs degree murder and sentenced to life in Marquette. He died in prison in 1981, the year I was born.
