Ghostbusters Teaser Trailer Theme Fan Remake

(Disclaimer: I don't own this song or Ghostbusters. Full credit goes to Glenn Hughes and Pat Thrall. I'm just a Ghostbusters fan. Thanks.)
Here it is, my fanmade rendition of a full-length version of the original "teaser" theme originally made by Hughes/Thrall that can be heard in the teaser trailer for Ghostbusters. Two things: Because I've never heard the full version before, I had to "fill in the blanks" with my own imagination to make it a whole song and there's no lyrics/singing in it because I don't sing well. But the melody of the verse and chorus can be heard throughout still. Hope you enjoy it. Happy National Ghostbusters Day! And check out Zack Myers' (ZackGB) MIDI version of this theme, which inspired me to do my own remake!
(UPDATE: TexasFilmCritic brought it to my attention that this version was not actually made by Glenn Hughes/Pat Thrall, which was also stated by Spook Central as well. Thanks to TexasFilmCritic for the clarification!
This video is dedicated to the memory of Harold Ramis.
