Aerosmith -- good but too patchy... unless your a teenage american girl, in which case they still rule apparently...
Deep Purple -- it's all about Highway Star, the version off Live in Japan. Amazing. Jon Lord!!
Thin Lizzy -- great but they were a pop band. And all the better for it.
The Stones are obviously fairly irrelevant to the canon under construction. The Stones were great but they're only tangentially connected with the others listed. Same for the Clash, who were The Greatest Band Ever.
Leaving out da Zepp is just puckish. Sure half of the Song remains the same is rubbish (lets leave my opinion on Page's ontological position to one side

) but then so is that Led Zepp live DVD from last year. Maybe I should give it another go with the new DVD player but -- holds nose -- phew! The thing to bear in mind about Led Zepp though is that, like AC/DC, they were FUNKY AS FUCK. One day I WILL have two copies of Back in Black to scratch the fuck out of. And if you haven't got down to Custard Pie or Misty Mountain Hop you haven't lived.
The Stooges -- awesomely transcendent. But they were very clearly an
acid house band before their time. They were from Detroit and everything. I refuse to budge from this position and Dr Beck is with me on this one.
I'd just like to mention Frank Zappa's Stevie's Spanking in passing.
