I was curious about the trademark implications of calling anything a palooza. Turns out you can get away with it:
"I did have a happy thought in my heart to know that it has become part of the American vernaclular, with all these funny paloozas," the festival founder and Jane's Addiction frontman said recently. "I'll share a funny story with you. Early on, as people started to kind of use the palooza aspect of it, typical to lawyers, I was getting calls all day long from a lawyer: 'Somebody's calling themselves 'Clamapalooza' and they're doing clams and oysters. Somebody's doing Waterpalooza; they want to make a bottle out of it. We've gotta stop 'em!' And I was at first really taken aback and I was put on my heels about it. But they were calling me all day long and I stopped and I thought about it. I said: These guys are probably making so much money trying to shut these 'palooza' people down. Better I should let 'em do it. Because I don't intend on paying these lawyers all this money, No. 1. And No. 2, it's actually advertisement for Lollapalooza. So I said, 'You know what? Don't bother 'em. Unless they're calling it Lollapalooza, leave 'em alone and don't call me.' And you know, it really did work out."
