Everyone knows a bit about Charles Manson and none of it is positive. Very few people, however, know that he is a musician and songwriter. I have always been a big fan of Guns n' Roses and owner of most of their albums, one of which the 1993 cover album The Spaghetti Incident?, which features covers of punk and glam rock songs from the 70s and 80s.
One of the songs, track 13, or rather the unlisted, hidden second part of track 12, "I Don't Care About You", is a song titled "Look at Your Game, Girl" and was composed and originally sung by none other than Charles Manson. Axl Rose was the only member of Guns n' Roses who wanted to include this song. For obvious reasons the rest of the band protested but the song ended up being recorded, albeit with only Axl performing.
I found the original song by Manson on YouTube:
I must admit he doesn't have an unpleasant singing voice..
