Way more, right? This was Englishtown, and there were reportedly 100,000 shirtless fans there. In 1992 alone, they played 13 stadium-sized shows; add those two together and you’re pretty close to a million.
You can do the math. Getting the numbers would require tedious research, and more than some guesswork, but this isn’t the Drake equation: there are actual figures available. The back of the envelope looks like (Number of shows) X (Average attendance) but that’s leaving quite a bit out; you need some sort of coefficient in there to account for repeat customers. The math is doable, though.
How many was it?

Living near the University of Pennsylvania I know for a fact that the technical term is “shit ton” just a little bit more than an “ass load”
Is a shit load somewhere in between? We don’t have those other measures in Oz, possibly a result of switching to the decimal system in the middle of the last century.
If you wanted further graduations, crapload (on the lesser) and fuckton (on the greater) would be acceptable.
