Bob Dylan & Johnny Cash

During Bob Dylan's Nashville Skyline sessions country legend Johnny Cash stopped by to visit. A friend and label-mate of Dylan's as well as an early supporter of his music, Cash had been recording next door with his own band. The two wound up recording a series of duets, covering Dylan's "One Too Many Mornings" and "Don't Think Twice, It's All Right" as well as Cash's own "I Still Miss Someone." None of these were deemed usable, but Cash returned the following day to record more duets.
