Paul McCartney’s follow-up to his McCartney album was an album accredited to not only himself but also his wife Linda. Ram was released in the U.S. on May 17, 1971 and sported the hit single Uncle Albert/Admiral Halsey. As a promotional strategy, Paul decided to make separate mono mixes of each track on the album, designed specifically for AM radio airplay and send out a promotional album in very limited quantities to radio stations that were not broadcasting in stereo. As with some earlier Beatles mono albums, these were not simple fold downs of the stereo tracks but actually were unique mixes that in some cases differed considerably from their stereo commercially released counterparts.
