As someone said they helped out Skid Row and Cinderella, and not just in the 80's Skid Row used Jon's Studio to record part of their last album.And the boys are definetly like Def Leppard and Aerosmith( though I'm wouldn't put them as an 80's band a lot of people do).
But i can also understand how they would want to distance themselves from that, it's not the 80's anymore and if they would bring out Skid Row on tour that would probably do more damage for them than good.
