Johnny Cash appeared on the Columbo episode Swan Song playing a musician named Tommy Brown who kills his odious wife. One of the memorable songs he played in that episode was the song I Saw The Light, which was originally recorded by Hank Williams in 1948. It become one of his most popular gospel songs. While many like the Columbo version of that song, it has never been officially released as a single. There are some postings of it on the Internet which likely are not legal. However here is a performance of that song with his wife, June Carter Cash, on the Johnny Cash Show which ran from 1969-1971 on ABC. Enjoy and have a nice Sunday everyone.
