Mick Jagger has hinted the Rolling Stones might play the same set list at Saturday's Hyde Park gig that they played first time round in 1969 - but there will be no repeat of the stunt that saw him release hundreds of butterflies into the crowd.
This weekend's performance comes almost 44 years to the day since they played the famous free concert in the central London park.
That gig, on July 5 1969, was only two days after the death of founder member Brian Jones and marked the live debut of his replacement guitarist, Mick Taylor.
The singer told Absolute Radio's Pete Mitchell: "Obviously, the same set list is going to be used, it saves me having to think."
The 1969 gig kicked off with Jagger reading extracts from a poem by Shelley in tribute to Jones, the band's founder, who was found dead in his swimming pool at home.
Jagger admitted that this time the songs might be played "in a slightly different order", saying: "I'll put them in the butterfly boxes and then throw them in there cut out and then shake them and then see what comes out and in what order."
He said there would be no butterflies released because they "didn't go down very well last time". He said: "I think we got a lot of complaints from the park because they didn't know we were going to do it and they were, of course, the wrong kind of butterflies and they went on to eat the wrong kinds of... Anyway they weren't happy."
The stage at Hyde Park is being covered in model oak trees in a nod to the first time the rockers played at the venue. The Sun reported that the 70ft fake trees have been planted on top of the stage to recreate the feel of their performance in 1969.
A source said: "When Mick and the band looked out from the stage back in the Sixties all they could see was a sea of people and a load of trees, but many of those have been cleared or replanted since. So they want to recreate the woodland. As you can see from the pictures, the two oak trees either side are absolutely massive. They want it to look as authentic as possible."
