thousands of butterflies in memory of Jones before opening their set with "I'm Yours and I'm Hers", a Johnny Winter number. The concert, their first with new guitarist Mick Taylor, was performed in front of an estimated 250,000 fans. A Granada Television production team filmed the performance, which was broadcast on British television as The Stones in the Park. Blackhill Enterprises stage manager Sam Cutler introduced the Rolling Stones onto the stage by announcing: "Let's welcome the Greatest Rock and Roll Band in the World." Cutler repeated the introduction throughout their 1969 US tour. The show also included the concert debut of their fifth US number 1 single, "Honky Tonk Women", which had been released the previous day. The Stones' last album of the sixties was Let It Bleed, which reached number 1 in the UK and number 3 in the US.

Part of the tour, and the Altamont concert, was documented in Albert and David Maysles' film Gimme Shelter. In response to the growing popularity of bootleg recordings (in particular Live'r Than You'll Ever Be, recorded during the 1969 tour), the album Get Yer Ya-Ya's Out! was released in 1970. Critic Lester Bangs declared it the best-ever live album. It reached number 1 in the UK and number 6 in the US. At the end of the decade the band appeared on the BBC's review of the sixties music scene Pop Go the Sixties, performing "Gimme Shelter", which was broadcast live on 31 December 1969. The following year, the band wanted out of contracts with both Klein and
