"The Rover" by Led Zeppelin....one of the greatest!! in Electric Guitars Posted December 20, 2008 They certainly did play the entire song live! They played it, and several other songs from this album in Cincinnati, and I assume the entire tour sometime in the mid 70's. Sorry I can't remember the exact year. The 70's were a little fuzzy. As someone else pointed out, they often played new songs live before they were released. They were almost constantly touring and new songs for the next album were frequently recorded between live shows. They would "practice" the new songs live and even fine tune the song on the road before going into the studio and laying down the track which was performed with the "live" energy they were accustomed to playing it with. There were even a few songs that were recorded in the studio in one take.
