He's estimated to have made $10-12m in the 80's.

I had some of the details wrong btw, you had to mail in $120 for the chance at 4 tickets, and he only held it for 6-8 weeks. Part of what was so shitty though was that very many of his fans couldn't really afford what was about a months rent but scrapped it together anyways. Maybe it was a poor financial decision on their part, but he took advantage of those people for his own profit, when he didn't even really need the money.
