I remember when the show was on ABC for three seasons. Third season, when he realized the show was not going to be renewed, Cash booked a lot of performers he wanted to present as opposed to those who would bring in ratings. That last half of the third season he had Eric Andersen and Ramblin' Jack Elliott, along with Derek and the Dominoes on the same night. Also on another show, had Gordon Lightfoot singing Canadian Railroad Trilogy. I think the show wrapped up in 1971 0r '72.
