What and when is the largest concert performed in terms of paying attendees?
I don't know whether this still stands, but the Guiness Book of World Records at some point listed a-Ha's performance at the 1991 Rock in Rio concert as the record holder with 198,000 paid attendance.
Copacabana (Rio de Janeiro), Rio de Janeiro, New Year's Eve 1994 featuring Rod Stewart with an attendance of 3.5 million.
1a) already mentioned & b) paying attendees is the question. That aside, I bet it was difficult to hear anything from the back :P– TetsujinMar 12, 2015 at 19:35
@Tetsujin you must have missed the time showing on rite side of profile picture of answered person. And when i submitted the answer, this example was not there. Maybe few seconds early or late. Mar 12, 2015 at 20:32
ah, yes - for me, I saw one this morning, the other [yours] this evening. I didn't check the timestamps, tbh.– TetsujinMar 12, 2015 at 20:36
