How would I feel if Rush got a new drummer? And then a new bass player two years later? And then later a new guitarist a year after that? And these three imposter wannabes kept on touring and recording as Rush?
Well... I can't predict how I'd feel. By their fruits ye shall know them. If these guys somehow kept the spirit alive and they actually felt like Rush when they played, I'd probably enjoy them and be fine (though always pining for the "good old days" of Rush like I already do

I remember when the Drama album was released as a YES album and Trevor Horn was singing on it instead of Jon Anderson, it just felt all wrong. The spirit (or soul) of the band just wasn't there. It was a good album, but it didn't feel like YES at all and I thought it should have been called something other than YES. But there might be a singer out there that could keep the spirit of Jon Anderson. Who knows?
