It looks like Genesis is going back out on the road. Phil, Mike, and Tony will be doing 20 shows in Europe and 20 in the US for the "Turn It On Again" tour of 2007. Originally, the five members from the classic '70s lineup met to see if they could schedule a set of shows of "The Lamb Lies Down on Broadway", but Peter Gabriel declined due to scheduling conflicts. With Peter out, it didn't make sense to include Steve Hackett as the four member version of Genesis was only a tiny slice out of their history. You can view their news conference where they discuss all of this from this shiny link.
