McCartney mixtape: Superb Weirdness

This is a mix of unreleased McCartney tracks, all recorded between 1977 and 1979. Just for reference: McCartney made THREE Top 10 albums in this period (London Town, Back to the Egg, McCartney 2). He also had a #1 single in 1977 (Mull of Kintyre), another #1 in 1978 (With a Little Luck), and ANOTHER #1 in 1980 (Coming Up). These songs are just.... extra.
