The Rolling Stones will not decide the final setlist for their Hyde Park return tonight until just before the show -as they are still trying to agree on the songs, Keith Richards has revealed.
In an interview for Absolute Radio, guitarist Richards said : "We are still differing about certain songs and stuff, and also we have to think that we have another one coming up....and what we want to do next week.
"So, there is still a bit of juggling going on. But, I mean those things can be decided on the night."
Tens of thousands of fans stream into the outdoor venue this afternoon in anticipation of the band's headline performance, 44 years after they last played.
Tonight's show - part of the Barclaycard presents British Summertime - is the band's first appearance at Hyde Park since they played a celebrated free festival there in 1969.
It was the band's first appearance since the death of former guitarist Brian Jones, and featured the first performance by his replacement Mick Taylor - who will also take a guest role tonight.
