Marianne Faithfull's first hit, "As Tears Go By," was recorded when she was just 17 years old after she met with the manager of the Rolling Stones at a party.

Marianne Faithfull, the songstress who helped spur music's British invasion and was a muse to the Rolling Stones, died Thursday at 78.

She and Jagger began dating in 1966 and became one of the most glamorous and notorious couples of 1960s “Swinging London.”
