I was thinking the same, but JB was more a musician's musician, and BTO is the everyman's band. I mentioned to my wife the other day that Beck had passed, and she said "who?"
The pop world was also too quiet when we lost Chris Squire, John Wetton, and even Keith Emerson. Peart was one of the few of that crowd that
almost got the wider recognition he deserved.
There's a funny story about JB from one of the members of Pink Floyd. It's been a long while since I heard it, so I forget the details, but basically they had wanted to ask him to join them when they had lost Syd Barrett. But they thought he was too good for them, and so they were afraid to ask him!
