While working on the Beatles Anthology project, Paul McCartney was reminded of the band's more carefree, youthful days when they had more time to spend together as friends and contemplate life. He wrote the song while on vacation in Jamaica in 1995. He explained in the album's liner notes: "I was remembering the '60s; sitting around late at night, dossing, smoking pipes, drinking wine…jawing, talking about the cosmic solution. It was what we were all doing… all that, 'What about... wow!' It's that time in your life when you got a chance for all that."
This features McCartney playing a double bass that was originally owned by Bill Black, who played it on several early Elvis Presley hits, including "Heartbreak Hotel."
Lily Allen wrote "Something's Not Right" for the soundtrack of the Peter Pan prequel, Pan. The song was inspired by the heartache that Allen experienced after suffering a miscarriage when she was six months pregnant with her first child by husband Sam Cooper in 2010.
