Frampton got stuck with the "pretty boy" handle...because he was a good looking guy and chicks dug him.
It overshadowed his trememdous talent as a writer, guitarist, and innovater.
It wasn't "cool" to like frampton if you were a teenage guy in the 70's...I know, I was one. I liked him, said so, and got the "teeny bopper fan" flack from my buddies.
Im glad he is getting his due now days.
