Fascinating insights into the life of Mick Jagger via love letters sell for double their estimation, reaching over £180,000 for all 10 letters, The Telegraph Reports. 

The letters, written in Australia during the filming of Ned Kelly portray Jagger as a "poetic and self-aware" 25-year-old, and capture a "vivid moment in cultural history" as he dotes on Marsha Hunt, who he enjoyed a secret relationship with. Jagger tells Hunt: "I feel with you something so unsung there is no need to sing it." He also thanks the singer, who was 23 at the time, for being "so nice to an evil old man like me" while providing an insight into another British powerhouse emerging that the time, The Beatles, moaning of "John & Yoko boring everybody". Gabriel Heaton, Sotheby's books specialist, said: "These beautifully written and lyrical letters from the heart of the cultural and social revolution of 1969 frame a vivid moment in cultural history. "Here we see Mick Jagger not as the global superstar he has become, but as a poetic and self-aware 25-year-old with wide-ranging intellectual and artistic interests."

While cultural artefacts, which depict the inner workings of those we idolise today, are fascinating enough, the fact that these letters have sold right in the middle of The Rolling Stone's big come back tour provide a pertinent reminder of the indifferent business that made them famous.
