I found this newspaper photo in the Hightower family collection. I don't have a precise date, but my best guess is sometime in the late 1970s. Frank DeLaro is a '65 graduate of Dulles High School. I'm not sure if he still works in FBISD. (I don't know Ronald Hartman.)
I'm sure you recognize Frank on the left in the bottom row in the picture below. That's Bill Knox next to him & Charles Hauerland on the right. Next row up from the left is Ronnie Adler & Bill Tise. The apex of the group is Van Brock. I think the drum major in the background is Wayne McCormick.
