Here are some figures from Rolling With The Stones:

US 1969 335000 not including Hyde Park or Altamont
Europe 1970 200000
Uk 1971 34400
US 1972 750000
Pacific 73 185500
Europe 1973 307700
US 1975 1000000
Euro 1976 554000 not including 200000 Knebworth
US 1978 767189
US 1981 2195071
Europe 82 1665560
US 1989 3010099
Tokyo 1990 500000
Europe 1990 2429000
Voodoo Tour figure not given, I estimate around 5000000
Babylon tour 4600000
No Security not given
Licks Euro 1625496
Licks NA 1506961
Licks Asia 333539 Licks figures from CD liner notes

The above figures add up to around 27,000,000 not including Altamont/Knebworth or Hyde Park. Not sure what figure would be accurate for No Security tour, possibly around 1.5 million? I don't know if the Licks NA would include the SARS show, probably not, which would add another 500K.
If you guess that Altamont/Hyde/Knebworth total around 1 million, then the total from 1969 to present would be approximately 30 million.

So the next post should be : how many people have never seen the Stones ??? Millions and Millions , several hundreds of times...

and the same dopes will tell how many they have been too & which ones they liked the best
