You can't put a price of fun, as the old saying goes. However, in a new interview, Steven Tyler of Aerosmith believes he knows how much money he spent on cocaine in his wilder and crazier youth.

TNT is reporting that, during a feature on an upcoming Australian edition of '60 Minutes' the Aerosmith frontman was confronted with the rumor that, over the course of his career, he blew $20 million on blow. Tyler came back with a smaller figure.

"No, probably, realistically, 5 or 6, easy," he said. "But it doesn't matter. You also could say I snorted half of Peru, but, you know, it's what we did." Of course, Tyler is specifically talking about how much he snorted. It is not known if he has ever partied with Rod Stewart, who took cocaine anally.

Australia's '60 Minutes' has spent quite a bit of time with classic rock stars lately. Last week, they profiled Robert Plant, where he hinted at the possibility of a Led Zeppelin reunion in 2014.

Last year, Aerosmith appeared on the original American version of the popular long-running news program that exposed the band's internal squabbles. Bassist Tom Hamilton blamed reporter Lara Logan's cleavage.

“She had a very low-cut top on," he said. "I’m like, ‘Okay, this is sort of, ‘Get the band nervous with your cleavage and make them say stuff.’ And if you go and watch the interview, you won’t see that. So I’m like, ‘Ahh, that’s how they do it.’ They show their boobs and get you to talk about stuff. And then, there you are...It works every time.”
