Johnny Cash was a consummate professional during good times and bad, and this complete, uncut 50-minute set from the long-running PBS concert series Austin City Limits shows the Man in Black in fine form, recorded at a time (January 3, 1987)

Recorded on January 3, 1987, Live from Austin, TX is Johnny
Cash’s performance from the Austin, Texas television show,
Austin City Limits. It was released on New West Records in 2005.
Cash performs many old hits, and performs new ones from his
latest releases on Mercury Records, where he just recently moved
to. The CD and DVD do not contain the whole show — the songs
“The Big Light”, “A Wonderful Time Up There”, and “The Fourth
Man in the Fire” were left out.
