Griffin Dunne

Griffin Dunne is a friend of Glenn Tipton who lives in a neighborhood near Tipton Village. He gets together with Glenn every Wednesday to play cards. He bears a resemblance to Ritchie Blackmore, and it is still unknown if the two are related or not.

He has a character based off of him in the book series Denim and Leather, an English teacher named Griffin Black (you see what we did there?).
