Boston- Haven't done anything good in 30 years and without Brad Delp, it just isn't the same.
Skid Row- No Bach, no dice. They are essentially a tribute band featuring three original members.
Stone Temple Pilots- See above. They could prove us wrong, like AIC, but I am not very optimistic.
Aerosmith- Should have retired years ago.
Def Leppard. The band died with Steve Clark. Should have called it a day 25 years ago.
RATT- So there are two bands called RATT, one with 3/5 of the original lineup and one with just the drummer and a bunch of scabs. Good grief.
