OK…here’s another one…
80’s slasher movie set at maybe a carnival, fair or some other end of school festival in a dark wooded park area with a pavilion or decorated tent. Not much else I remember except for towards the beginning there’s a party with a live band that looks like a bunch of undead gangsters that plays that 80’s retro rockabilly and had a stupid name like the Corpse Devilles (don’t hold me to that).
Note: ‘The Funhouse'(1980) seems like a good possibility but not totally…and…band could be John Carpenter’s Coupe Devilles but they never did the costume thing.
“Funland”(1987)?
No, not “Funland”. That was an amusement park.
“Death Screams”(1982)? Also known as “House of Death”.

Just guessing, never seen it. Kiss Meets the Phantom of the Park.

So I stumbled across the answer by accident. Read a posting called
reallyawfulmovies.com/2016/04/18/10-most-memorable-horror-movie-musical-performances/
and…boom…#9 answered my question.
The movie is Graduation Day (1981) and the band is Felony doing the song ‘Gangster Rock’.
They’re actually in some sort of ‘indoor/outdoor’ roller rink in a dark park (which I guess reminded me of a carnival tent). I have NO idea where I got the name of the band from.
Note: Apparently Felony had a minor hit in the early 80s with a song called ‘Fanatic’. Sans undead gangster outfits!
Glad you found it and thanks for letting us know!
