You guessed wrong. You saying "I guess someone doesn't have to be very good at something" doesn't mean someones not very good at something. That's just your opinion and I respect that, you idiot!
We used to go see MAB (when he played in Holland) in the bars around northern Illinois/southern Wisconsin in the 80's
Peter Green. My musical sensibilities snapped into focus the first time I heard the original line up of Fleetwood Mac.
I saw some footage on YouTube of Chicago playing at Tanglewood. He was amazing. There was a documentary aired on CNN last Sunday. Now More Than Ever: The History of Chicago. Walt Parazaider said that Terry could play rhythm, lead and sing simultaneously. He told a story of the band playing a gig in a club in LA just as they were making a name for themselves. He was packing up his saxophones and he felt a tap on his shoulder. He turned around and it was Jimi Hendrix. "Walt, the horns are like one set of lungs, your guitar player is better than me." If you missed it, the rebroadcast is on CNN at 8:00 PM this coming Saturday.
