Fp, I think Glenn looked good no matter how his hair was, but I was a 70s girl and the best memories for me are from that era. I've always loved long hair on young guys. But they have to have the looks to go with it. I wouldn't have wanted to see him with long hair after the early 80s. Glenn became classy then.
My My, that reminds me of a boyfriend of mine back in the day. One night he came to pick me up and had had to cut his hair for football. It was over with him for me!
I've never seen the flag shirt pic!
