The guy on the right with the guitar is my dad, circa 1973/74; the other guys band members.
He got this out to show us his superior teen facial hair, but it's actually kind of startling to see him with such a thin beard. He looks like all the guitar playing punks who grow their hair out *now* because they're still into the same bands.
Vote:
1) totally looks like you, Red
2) I thought you were adopted until I saw this picture
3) can't see anything past the bell bottoms and plaid
