Vint70s-Lvr: The moustached daddy is Dan Pace. Thanks to clues provided by Gods Amongst Men, I believe I’ve identified the other dude as a young Lee Marlin. I saw the compilation picture on Tumblr, and just recently found the set below.
The scene takes me back to some happy days I shared in the late 70s with a slightly older but way more experienced “Buddy.”
