Me singing a Scooby-Doo medley like a pro for my upcoming video! (Patreon)

This is gonna be the end credits song in my upcoming video essay analyzing the entire franchise of Scooby-Doo. The arrangement, interments, backing vocals, and mastering was done by my good friends RKVC. All I did was sing. There are 5 Scooby-Doo theme songs in here. Can you name them all?

(Expect a bigger update about the video soon, along with some screen shots from filming!)
