Thanks for remembering this great all around musician.
Not only did his guitar drive those awesome Chicago horns, he had one of the coolest blues/rock voices going.
Gone but not forgotten.
Since “youtube” I feel in love with Chicago all over again, the Kath/Cetera music was the best and I watch them all the time.....I recently saw him in “Electra Glide in Blue” and Terry (small part) was great at the end...check it out if you get a chance.
