“I do hereby call to order the 103rd meeting of the Batman Mystery Club!”

Along with a brief visit on The Adventures of Superman radio show it seems there was almost a Batman radio series, only this Batman and Robin were nothing like any other version of the dynamic duo.

In the pilot for the radio series that was produced in September of 1950 Bruce Wayne is a kind of condescending pipe smoking dad who holds forth at The Batman Mystery Club where everyone knows he's Batman and he and his pal Robin (not Dick Grayson, this seems to be some guy named Robin) bust fake ghosts and mediums. You can listen to the only one they made below.

Batman Mystery Club

That's interresting.And by the way, the title of the episode is "The Monster Of Dumphrey's Hall".

But the series would have (as far as we can tell) been the Batman Mystery Club.

And if it had been put on the air after a while they could have gotten a Bat Van and Alfred and Vicky Vale could have come along and Ace the Bat-Hound could have been introduced early and the only thing Batman would have in his utility belt would have been Ace Snacks.
