Shawn Mullins recorded "What Is Life" for the soundtrack of the 1999 film "Big Daddy". Released as a single, it peaked at number 62 on the UK Singles Chart. In 2004, Christian rock singer Neal Morse included a recording on the special-edition version of his album "One", with Phil Keaggy as a guest vocalist. The track later appeared on Morse's 2006 album with Mike Portnoy and Randy George, "Cover to Cover", which also includes covers of "Day After Day", which Harrison produced for Badfinger in 1971, and the Clapton–Harrison composition "Badge".
