Ooh, ensemble shot. :)

I don't know if they had a logo per se. The Emergency! was usually in bold white, which wouldn't do for most iconning, I'd think.

Anyway, it doesn't matter. I have a handful of professionally done icons (your text included) and I've jury-rigged some of my own (b/w one up thread). I should be satisfied. It's not worth anyone jumping through hoops. ;)
