Sixty years ago (this Sunday) on the 1st May, 1956 Sun Records in Memphis released "I Walk The Line" by Johnny Cash.

It would spend six weeks at the top of the U.S. Country Juke Box charts that summer, and then reached number 17 on the Billboard Hot 100 music charts. 

Today's video is from the famous concert recorded in San Quentin jail in 1969. By the time of this concert "I Walk The Line" had sped up quite a bit from the original, which I prefer. 1969 was probably when I caught up with this song for the first time, because I'm sure it wasn't in 1956.

Look out for additional footage added to the end.

You wait weeks for a 1950s record and then two come along, back to back…
