The Beatles Top 60 Solo Songs: #9: “What Is Life”- George Harrison. Another song from George’s first post- Beatles album- All Things Must Pass. The second single from that album- it reached #10 in the Billboard Hot 100. There has been some debate as to whether the song is- a love song-to his wife Pattie or another one of Harrison’s devotional songs. This is another song that Harrison stockpiled from his Beatles days- it was written in early 1969 but not used.
