It's a tale of two Ghostbusters covers! Above is The Human Tim, who, as normally, does a good cover of a classic theme, but really shines when he gets to the guitar solo. And below is Matthew Jordan's more '80s-style pop-rock version.
Both covers are excellent, but I think we need to get these two together and force them to record a third version of the Ghostbusters theme. Between Matthew's voice and Tim's guitar, I imagine Ray Parker Jr. would weep to hear it.
