I don't know if Phil Collins is Advanced or not. If you think early Genesis was the greatest thing ever, then you probably would have to say it is. As for me, I haven't listened to the early stuff much. One thing I can say, though, is that I have always loved "Take Me Home" and "Easy Lover." I like "Abacab" and "Paperlate" and some others from the Genesis days. I often find myself singing "No Reply at All" and "That's All," and I wouldn't change the channel if "Illegal Alien" were to come on. There are plenty of songs by him that I really don't like, especially "In the Air Tonight," but I would stack his best solo stuff against Sting's any day. He's also a pretty good drummer.
Were it not for the Advanced Theory, I would probably be embarrassed to admit all this.
One other thing: One of my favorite running jokes from "Late Night With David Letterman" was from back in the eighties when Phil Collins had a million hits. Letterman would always say something like, "Paul, you know who I'd really like to hear on the radio? Phil Collins. If only they'd play one of his songs every once in a while." Then Paul would play along, of course. I always thought that was funny.
