Glad I rediscovered this cartoon on Boomerang. I remember seeing this syndicated series Fridays on KPRC (NBC Houston), then switching it to The Brady Bunch.
The show was way ahead of its time. Having a neighborhood watchdog club (loved that old lady!) defending against the Russians. Jack Burns was a hoot playing Ralph, with all his crazy theories about the communists!
This prepared Tom Bosley when going on to Happy Days, playing a square father. Before Tommy Bradford and Buddy Lembeck, Willie Aames was the 2nd voice of Jamie Boyle.
Lennie Weinrib was the 2nd Chet. It was the only time Lennie replaced someone, because he got replaced twice voicing Scrappy Doo (Don Messick) & Freddy Flintstone (Scott Menville).
