Her success in the 1960s included the hit song As Tears Go By, which she co-wrote with her then-boyfriend Mick Jagger. The couple can be seen together in a picture taken in Sydney in July 1969.

 Faithfull began her singing career in 1964, after being discovered by Rolling Stones manager Andrew Loog Oldham.

In 1965, she introduced her first album titled after herself. The album included her UK top ten hit single and another single that reached number four, Come And Stay With Me. Simultaneously, she released her second album, Come My Way, which mainly consisted of folk cover songs.

From 1966 to 1970, Faithfull was in a highly-publicised relationship with Sir Mick following his split from model and actress Chrissie Shrimpton.

One of her first successful songs, As Tears Go By, was written by Sir Mick Jagger and Keith Richards. Following this, she released a string of hit singles, including Come And Stay with Me, This Little Bird, and Summer Nights.

She was famously found wearing nothing except a rug at an infamous drugs bust at Rolling Stones guitarist Richards’ country house, Redlands, in 1967.

Following her split with Sir Mick, Faithfull spent two years on the streets of Soho while addicted to heroin before living in a squat.

She returned to release an album, Broken English, in 1979, which is now regarded as a classic.

Faithfull re-invented herself in 1987 as a jazz and blues singer, with the critically acclaimed Strange Weather, and in the same decade went into rehab.

Recently she has enjoyed a resurgence and is said to be admired by the likes of Kate Moss and Courtney Love.

The daughter of a British military officer and an Austro-Hungarian Jewish baroness, Faithfull recently appeared in Sofia Coppola’s film Marie Antoinette.

She made guest star appearances as God in the TV sitcom Absolutely Fabulous.

Early films included I’ll Never Forget What’s ‘Is Name, alongside Orson Welles, and Girl On A Motorcycle.
