Hehe. Found this snippet online with a list of potential replacement singers.
Sammy Hagar
"Few things are worse than the music of Aerosmith. The music of Sammy Hagar is one of them. It's a scientifically proven fact that no band has ever improved after the addition of Sammy Hagar. A swift high-pitched hhhHHHheyyyyy-a! is it all takes for Hagar to effectively lop the balls off any rock band. Perhaps that's what it'll take for the world to see what a wimpy-ass band Aerosmith truly are at their core. Also, he'll make them look young."
