This Day in Music — August 22

1968 : Having come home from vacation to find her husband in bed with Yoko Ono, John Lennon’s first wife Cynthia files for divorce — one day before their sixth anniversary.

1970 : Derek and the Dominoes begin recording their famous album, Layla And Other Assorted Love Songs. The band features Eric Clapton, who in an attempt to lay low, downplays his involvement in the band.

1998 : With Hugh Grant and Elizabeth Hurley in the audience, Jim Carrey joins Elton John on stage at a show in Anaheim, California, where the pair duet on “Rocket Man.” After a reasonably straight rendition, Carrey sits at the piano and smashes his head into the keys.

2012 : Presidential candidate Mitt Romney becomes yet another Republican candidate banned from playing any cool bands at his events, after Dee Snider of Twisted Sister protests his using the band’s songs. There is a long history of bands squaring off against Republican campaigns appropriating their music.

2012 : Rap star LL Cool J hears his alarm go off one night in his Los Angeles home and rushes downstairs to confront an alleged burglar, name of Jonathan Kirby. One broken nose, jaw, and rib later, Cool J has subdued the intruder and police are on their way to take the suspect into custody. No word on whether Cool quoted one of his own songs, “Mama Said Knock You Out,” during the altercation.
