Mick Jagger and Keith Richards shed light on how they decide it's time to ramp up for another string of dates: (Mick Jagger): "It sort of runs in a pretty good cycle." (Keith Richards): "I have to wait for a phone call from Mick, saying, 'I'm getting a but antsy (laughter) -- you wanna go, and should we. . ." (Jagger): "Don't forget, there is. . . You gotta be a bit hard-headed, there is a sort of supply and demand thing here. If no one called up and said, 'We think, y'know, you should go and tour. . .' There's good times and bad times to do tours. (Richards): "In a way, Mick and I get the same feeling just around the same time. It's then -- as Mick was just saying -- y'know, does all the rest of it fall into place, y'know, the business and the supply and demands and all of that. But, basically, we say, 'Well, we're ready -- if the demand's there, we'll supply.'"
