Glen van Vliet
From The Real Frank Zappa Book: "I spent more time with Don (Captain Beefheart) Van Vliet when I was in high school than after he got into 'show business.' He dropped out during his senior year, because his Dad, who was a Helms Bread truck driver, had a heart attack and 'Vliet' (as he was known then) took over his route for a while -- but most of the time he just stayed home from school. His girlfriend, Laurie, lived in the house with him, along with his Mom (Sue), his Dad (Glen), Aunt Ione and Uncle Alan. Granny Annie lived across the street."
