Just a few days ago I watched the 1990 Serious Hits Live DVD for the first time since maybe eight years. Well, I was completely blown away by the power of the performance! Phil and all his band members seemed almost hyperactive to me! That was really nice to see. I also noticed Phil smiling every now and then in a way that made me think he was actually feeling good and enjoying himself. As we all know this hasn't always been the case for him.
Regarding his current tour I agree it's sad to see him performing sitting. But, I think the appearance could be much better. If he's supposed to be performing sitting, they should not use any bloody cheap office chair they happen to find, they should design a chair specifically for Phil's needs. The chair should be higher, and it should be more mobile. Also, the chair must be designed to give him a better posture, which will enable him to look more active and perhaps also bring more power to the singing. The key term is ergonomics!
I've been a fan of Genesis (and solo careers) since 1991. I was 16 then and now I'm 43. I realize that I'm now older than they were when they released We Can't Dance. That's a very simple and undisputable fact, but it doesn't make it any easier for me to grasp or accept emotionally. And the same goes of course for the 1990 Phil solo show I watched the other day: last time I watched it they were older than me. Anyway, I still like all the music as much as I did when I first discovered it. All this lovely music will stay with me for the rest of my life, and since I'm 25 years younger than them I understand that they will not be with me forever. When it comes to Phil's current tour, I think the feeling is there and that's what's important, even though the actual performance may not be as perfect and dynamic as on previous tours. I'm just glad he's well enough to actually do this tour. I have watched some clips on Youtube and noticed a great improvement in the performance, which I think is promising.
