LIKE any young lover Mick Jagger couldn't always get satisfaction.

But a private collector certainly has after snapping up 10 love letters from the Dartford-born Rolling Stones frontman to a 1960s muse for a cool £187,250.

Sotheby's said a phone bidder won the items penned to singer Marsha Hunt.

American-born Ms Hunt was the inspiration for the Stones' 1971 hit Brown Sugar and bore Jagger's first child, daughter Karis.

The letters were written in 1969 from the Australian set of Jagger's film 'Ned Kelly' and touch on everything from the moon landing to John Lennon and Yoko Ono.

They had been expected to fetch between £70,000 and £100,000.

Sotheby's books specialist Gabriel Heaton said the letters reveal "a poetic and self-aware 25-year-old with wide-ranging intellectual and artistic interests".

At a show in the O2 arena last month Jagger joked with fans: "It has taken us 50 years to get from Dartford to Greenwich".
