This home-recorded charmer is the most humble No. 1 album in pop history. In 1970, Paul McCartney was ostracized from the rest of the Beatles and was holed up in a shack with his family on the Scottish coast. Filled with anger and frozen by the legacy of the Lennon/McCartney partnership, Macca decided just to record for fun, setting the stage for the rest of his solo career. Bypassed at the time, the future hit "Maybe I'm Amazed" is an autobiographical marvel (as is "Every Night"). "Junk" is a real beauty -- like "Teddy Boy" it was ixnayed by Lennon as a Let it Be-era Beatles song. Paul plays everything on this one.
