Thatis why they couldn't carry on !!!!!!! ok, they tried with peter and they did good!!!! because phill was all ready in the band, knew the music, can sing and a dam good drummer!!!!!!!, but one thing I couldn't undestand was, Why Mike and Tony continued calling themselves GENESIS AFTER THAT ANOTHER BIG FALLING?. Peter left and they did good
. Them Steve left and they did even better (
comercially speaking, not musically) and them Phil left and they thought that was going to be ok ( ok we do not need him ),but they were wrong. They felt foverer. Mike and Tony
need to go back to their roots (PROG) and forget all these
commecial sh*tt!!!
He needs a good wake up call !!!!and play his keys good ownce again!!!
I believe that if that Ian Anderson wouldn't never be the lider and singer songwriter of the Tull I think he would of fail a long time ago!!!!! as Yes did went Jon left them in the 80's .they couldn't never carry on calling the remaining current of member YES, and they did ,but it felt, because Jon is part of essience of YES even RIck and steve left they did ok for an awhile but it turned out to be garbage!!!!!!!!. Even BLACK SABBATH tried also when Ozzy left and again they felt!!!!!! too 
David did very good without ROGER, that is not PINK FLOYD
and ROGER solo carreer is not PINK FLOYD either, but the both did very good, maybe because they both wrote their on songs and sang them.
Same thing to Lake, Wetton, Hammill, OZZY, Robert Plant (His solo music i do not like it
)ect..... They did good because they wrote their songs and they sang them!!!! 
on the other hand no matter what other singer TONY and MIKE brings to sings GENESIS (specially old songs) music it will never GENESIS again!!!!!!!! periot............
MY SUGESTION IS THAT THEY SHOULD CALL THEMSELVES EVOLUTION !!!! BECAUSE GENESIS IS NOT GOING TO WORK!!!!!
