"The deep voiced lip sync routine was hilarious too"
I like the episode where he does sing that baritone or something in the Andy Griffith show; because Barney's voice is squeaky;
That same plot, seems repeated in one of the Gomer Pyle episodes, Jim Nabors singing for Sgt. Carter's. Sigh...
And I think, another plot from the Andy of Mayberry show was again repeated on the Gomer Pyle USMC show.
