May 2008. Sir Paul McCartney: I went for a walk, to experience life for a minute. There's a guitar shop I like to visit, so I went there & got chatting to the guy who works there. He said he had a left-handed mandolin to show me, & I ended up buying it. At home, I started stomping around the kitchen, playing this little instrument, just enjoying myself. I sang, "Everybody gonna dance tonight" and my little girl came running in & started dancing, so I fell in love with the song.
