Same here. And I don't know why Ross Jr. hasn't licensed the show to ME-TV or some other sub-network that runs classic TV. Very strange to ponder their thinking on The Alvin Show.
I didn't even consider my two favorite animated shows from the 1960s - Rocky and His Friends and The Alvin Show, but they both rank right up there with shows which have given me enormous pleasure for almost my entire life. (I just wish I could get the entire run of The Alvin Show.)
In no particular order:
Perry Mason
The Andy Griffith Show
The Dick Van Dyke Show
The Twilight Zone
Ellery Queen
The Mary Tyler Moore Show
Friends
24
The Good Wife
Elementary
