United Kingdom, April 12 -- Bill Wyman has been described as The Rolling Stones' most prolific womaniser.

A new biography claims the quiet bassist - rather than ladies' men Mick Jagger and Keith Richards - led the group's excesses when it came to bedroom antics during their early years.

The 89-year-old musician, who rose to fame as the Stones' bassist, is the subject of a forthcoming book by Bob Spitz, which revisits the band's 1960s tours and personal lives.

According to his account of the group, Wyman's behaviour during the band's first US tour in 1965 stood out amid an atmosphere already marked by widespread drug use and groupie culture, as the Stones became one of the defining acts of the era.
