'Like a Rolling Stone' started with rhythm of a waltz

Today's Morning Edition music is from 50 years ago Monday when in a studio in New York City, musicians began recording the sessions that resulted in what many critics consider one of the greatest rock 'n' roll songs of all time.

Bob Dylan has said the lyrics were pared down from 10 pages of angry verses that expressed the frustration he was feeling about the expectations of his fans and the direction of his career.

Initially, when he played it on the piano to give the other musicians a sense of what he was going for, the song was in 3/4 time, like a waltz.

On Tuesday we'll tell you how the hit version of "Like a Rolling Stone" was created.
