Yeah, Pat Dinizio passed away in 2017 (can't believe it's been that long already). He had health problems/injuries that had caused him to lose the use of his right hand and arm, and had gone significantly downhill prior to his passing.I was in high school when they broke out. Very good sound. I saw the lead singer passed away a couple years ago, he had gotten really obese which was a little shocking.
I loved their sound, have never figured out why they weren't bigger than they were. Dinizio had a great voice, and Jim Babjak was pretty underrated as a guitarist. Babjak has also written/performed compositions for a number of TV shows and movie soundtracks.
