Ronnie Wood said the Rolling Stones "won't be able to stop" touring if their 50th anniversary gigs are a success.
The guitarist said the band are sounding "up to and above par" in rehearsals in Paris. He added: "I can't believe how well the band is sounding."
Wood joined bandmates Charlie Watts, Mick Jagger and Keith Richards at the world premiere of 'Crossfire Hurricane' - the latest attempt to chronicle their lengthy career - at the London Film Festival.

They were joined on the red carpet by former Stone Bill Wyman who said he hoped the film captured the influence of founder member and guitarist Brian Jones who died in 1969.
Wyman said: "I'm glad he's remembered, that's the most important thing."
Hundreds of fans gathered in London's Leicester Square as the band walked the red carpet to a soundtrack of their biggest hits and the original R 'n' B tunes that inspired them.
The band will play to 40,000 people during their two nights at the O2 in London and will play two more shows in Newark, New Jersey, in the US, in December.
Wood said: "You would think it would be boring doing the same thing over and over again but it's not. It's totally fresh and totally new every time we get together. There's a chemistry between us every time we get together and I don't know what the hell it is but it's magic".

Asked about a possible tour, he said: "Once this wheel is turning I don't think it will be able to stop so hopefully the momentum it gathers by doing the O2 and the gigs in Newark, we won't be able to stop."
The film, made by director Brett Morgen, will be screened in cinemas in October and then broadcast by BBC2 later in the year. Tickets for the O2 gigs go on sale on Friday.
