jet, I think you may be taking them a little too literally. These guys are a lot of fun in concert, especially Rick Nielsen. The guy has some hilarious custom guitars, including one that looks like him, with his legs being the necks of the guitar, another with five necks (although, when I saw them play, I spotted what looked like one of those as a dummy, so just four working setups there), etc. The drummer looks more like a CPA than a drummer, etc. Just one of those bands that liked to laugh along the way while making some good music. About the only show I ever saw where the band appeared to be having more fun was a Jethro Tull concert.
BTW, aside from goofing around in concert, they also f'ing rocked the place. If you're in a band and had these guys opening for you in their heyday, you had better come out and play a good show, too, or these guys would have easily upstaged you.
Not my favorite band by any means, and not even in my personal top 20 favorites, but they have fun, and if you see them in concert, you probably do, too. Just my $.02.
