Quite possibly the weirdest thing I've ever come across is this record from a Weeki Wachee mermaid show from 1964-65, featuring the Alice title song with slightly modified lyrics, as sung by Marlin and the Mermaids! Gotta love that.
The Mad Hatter is truly frightening.
I've also found a few postcards to go with it, would love to find a brochure or program.
Unfortunately the vinyl is a little scratchy so there is some static.
Weeki Wachee is still in operation today, it has become a State Park and is now safe from closing - its fate was very uncertain about 5 years ago. If you are in Florida and nearby, go see the mermaid show, they are very fun.
