Who's Your (Science) Rock Star?

After I posted earlier on Joe Perry's bare-chested R.S.o.S. adventures, an interesting discussion crept up on Twitter. Let's say you had a scientific charity approach you for a lab photo shoot. Who would you want to invite? Chemjobber has already weighed in here. Personally, I trend towards more eclectic acts, so I'd be inclined towards TMBG (they did write a song about nuclear fusion, after all...).

So, readers, who would you like? More 'arena rockers' like Bon Jovi or KISS? Perhaps a socially-conscious musician like Bono? Classical, perhaps? (I think Yo-Yo Ma would look great in goggles). Or maybe someone more modern, like Will.i.am or Lady Gaga?

Voice your choice in the comments. Thanks!
