@Magicart87 and
@The Chatbox Ghost, I think Everybody was there just by virtue of its music video, which featured the Boys dressed like Gothic literary monsters (i.e Dracula, Frankenstein's Monster, a Mummy (Bram Stoker, author of Dracula, wrote a story about a Mummy that comes back to life, as did Edgar Allan Poe), and The Phantom Of The Opera) in a Gothic/Victorian-influenced setting.
Currently, I'm revising my CBJ Halloween and the playlist is mostly 80s songs with some 50s and 70s songs added in to diversify the sounds heard in the show. Here are said songs:
Weird Science (Wendell) (Wendell will wear a lab coat and goggles and he will be holding two beakers in his paws which he will pour into each other during the choruses)
Thriller (Romeo) (Romeo's outfit will be inspired by the red and black outfit MJ wore in the Thriller video with hints of Captain EO's clothing)
Ghostbusters (Henry and Wendell) (Henry gets a Ghostbusters-type uniform, but Wendell stays in his outfit from Weird Science due to there being 3(ish) Henry animatronics (Empty handed, guitar holding, and raccoon hat) and only one Wendell)
Dead Man's Party (Shaker) (Shaker will have a skeleton jumpsuit on his body)
Monster Mash (Henry with the Sunbonnets on backing vocals) (Henry will be dressed in an outfit similar to how Victor Frankenstein is dressed in the 1931 film adaptation's lab scenes)
I Put A Spell On You (Hocus Pocus Version) (Sunbonnets) (The Sunbonnets will be dressed as the Sanderson Sisters)
People Are Strange (Trixie and Gomer) (Trixie will be dressed as a ballroom dancer from The Haunted Mansion)
Season Of The Witch (Teddi Barra) (Teddi will be in a witch costume and her swing will be decorated to look like a flying broom)
The Devil Went Down To Georgia (Ernest) (Ernest will have devil horns on his hat and a golden fiddle in his hands)
Blood On The Saddle (Big Al) (Big Al remains in his usual outfit, but some jack o lanterns and hay bales are put near him)
Headless Horseman (Henry and the Bear Rugs) (A compilation of scenes from Ichabod and Mr Toad is projected in the background) (Henry's outfit in this song is based on the outfit Brom Bones wears in Ichabod And Mr. Toad)
Night On Bald Mountain (Gomer) (Similar to Headless Horseman, the Bald Mountain scene from Fantasia, sans Ave Maria, will be projected onto a screen) (Gomer will be dressed as the Phantom of the Opera)
