It's funny, I didn't know it was my former band-mates until a friend told me. But I knew Tony, Phil and Sandy (and Stephanie) were going to be professional musicians. That's how good they were in HS. Our band was pretty damn good. If I can find them, I'll post some audio clips. Be advised, they were recorded on a cassette tape recorder back in 1977 so sound quality is horrible.
Stephanie was also a very good singer in her own right. Very popular in HS as her beauty matched her talent. She was gorgeous. Lenny and Audrey didn't attend my HS.
As for Inside Out......you know, I never even noticed the similarities of the bassline as compared to Mark Adams playing back then. It wasn't until Sandy told me it was him. I then listened to it (40 years after it was released mind you) and said, yeah, it sounds like Mark Adams but there were some nuances in there that Mark never played. Wasn't any of his typical sounding licks. Yet folks swore it was Mark. I contacted the producer of the track and he ran down the story but that is was indeed Sandy on bass. Even Mark Adams thought it was himself. LOL
