McCartney (from the Mail on Sunday May 12, 2008): "I've always had a couple of voices. Originally you're just a kid at home, like everyone else, and then you start to dream of being a singer. My heroes then were rock 'n' rollers, so my ballad voice was based on Elvis and the screamy voice was me trying to be Little Richard. I loved him so much. When I joined the Beatles, John used to like that and it's stayed with me as something I enjoy doing - that gritty, souly voice. So on this track I was just thinking of how much there is to be grateful for in life, and I wanted to put that into song and use the gritty voice to do it with."
