I haven't heard of any sheet music for "The Frogs." It seems to me like there wouldn't be any because it a.) is not a well- known show and b.) didn't run that long on Broadway to become well-known. In some collection of Sondheim book there is "Invocation to the Gods and Instructions to the Audience" but I think thats it...I'm going to go check Google & etc.

there are, i believe two or three songs (Invocations, Fear No More, ?it's only a play?) scattered around in a couple of the colored sondheim books.
it's quite obscure, but i was surprised to find Fear No More
