The title track of musician John Lennon's Imagine sets him up as some kind of enlightened sage; but "How Do You Sleep?," from the second side of the LP, shows the ex-Beatle at his most petty. An unambiguous attack on Paul McCartney, his former songwriting partner and friend, "How Do You Sleep?" is totally out of sync with the way Lennon is often remembered today. Only a couple of years earlier, Lennon and McCartney had been friends, preaching a message of peace and love to society. What went wrong? 

When The Beatles broke up in 1970, the split was not a graceful affair for both the depressed fans and the bandmates themselves. The aftermath caused burning tension between former pals Paul McCartney and John Lennon, who ended up in a musical rivalry against each other. Lennon eventually poured his emotions out in a bitter song revealing his cruel thoughts about McCartney that would be called “How Do You Sleep?,” which would be one of the most brutal songs in history.
