Marianne Faithful had her first hit in 1964 when she was just seventeen. “As Tears Go By,” written by boyfriend Mick Jagger, would be her biggest hit. An original copy on London Records can get you $50.00. However, another song written for her by Jagger during her drug use is her most collectible. “Sister Morphine,” recorded in 1969 with the Rolling Stones backing her up and released on London Records, is worth up to $150.00 today.
