He's 64 this year. People try to claim he's lost it. I can imagine there are countless 64 year olds who would kill like this. Hell, I'm 37 and I'd kill to sing like that. That said, I still can't get used to him duetting Suite Sister Mary with his daughter. It's just a tad too weird with the sexual tension laden in that song.
Geoff still has the pipes and is always a joy to listen to, but his band comprised of 18 year old kids? Totally weird flex. My only guess is that the old dogs (pro musicians up in his age range) got tired of his shit.
