Rick, I'm not certain but I'm guessing the answer to your question is here. If that's wrong, at least you'll get to hear a great radio show.
I think Andy Devine replaced Smilin' Ed McConnel when Froggy the Gremlin moved from radio to TV but I don't think Devine did any of the radio programs.
"Plunk your magic twanger Froggy!"
"Hiya kids, hiya, hiya, hiya."
"That's my dog Tige; he lives in a shoe.
I'm Buster Brown; look for me in there too."
