Nobody in the band is going anywhere, people.
This but...
let rudess go if he wants to. i for one would LOVE to see derek back with the band. i loved his style of keyboard work for the short time he was with them.
controversial enough?
...but if Rudess did quit, I really wouldn't hold my breath for Derek being back in the band. Frankly, Rudess really elevated the level of complexity and musicianship when he joined the band, and I'm hard pressed to think of a keyboard player who could play Rudess' parts. But even if they did find one, I highly doubt it would be Derek. And even if they agreed to settle for someone not as insanely fast as Rudess, it has been a really long time since Derek has been in the band, so not only is there any evidence that he'd even be interested in coming back, I don't even think the band would think of him right away. I mean, it wouldn't be natural like, "Oh, let's just ask Derek to come back." People change, relationships change. They might not have musical chemistry anymore. Or he might be in a different place creatively, or maybe they really would like someone as fast as Rudess. Either way, Derek coming back into the band would probably be only slightly more likely than Kevin Moore coming back into the band.
