IMO to perform without rehearsal shows contempt for the audience, or at least a lack of care about what you do. Bands who busk it or who talk about playing it their own way without rehearsal and thought are rarely as good as they think they are. I saw an interview with Keith Richards where he said the Stones rehearsed for three months before their last tour, how often must they have played those songs?

I disagree, it totally depends what you're playing and I guess how good you are.
Neither of my two bands rehearse. The one is part of a collective, so who you go out with depends on who's available. Everything is written out, we just read it. A mix of notation and lead sheets.
The Stones would rehearse not necessarily the playing of the songs, there's an awful lot of technical stuff that goes on in shows that they have to get right. Cues and ends, lighting and projection etc.
