I suppose this is basically about "novelty songs", so my favourite is still this gem - The Ran-Dells, Martian Hop: Purple People Eater is brilliant! I also recommend Haunted House by Gene Simmons (not the Kiss guy) and the smash hit Monster Mash by Bobby "Boris" Pickett. Only last year I came across Naughty Naughty Naughty by Joy Sarney, a UK hit from the mid-'70s that I'd never heard before. Right off the bat I didn't like it but it has a great beat that drags you in ...
there's a couple Lookin for P***y by Dr Hook and the Medicine Show and The Mermaid by Great Big Sea https://www.youtube.com/watch?v=UDhCgAoggX8
WFIL, Philadelphia, Dan Donovan He plays it for the first time. It's done. Brief silence. he's hysterical. "That is the craziest thing I've ever heard!!! I'm playing that again!!" And he did. Programmed radio? Not back then.
