Ray Parker Jr.'s theme song for "Ghostbusters," including the now ubiquitous pop-culture query "Who you gonna call?", hit number one on August 11, 1984, and stayed at the top of the charts for three weeks. The song was the title track to the hit film, which starred Bill Murray, Dan Aykroyd and Harold Ramis as a group of parapsychologists who start a career capturing ghosts. The tune was by far the most successful song in Parker's career, though he also performed as part of a band Raydio in the late 70s and early 80s and spent some time playing with Barry White. It was also the biggest hit from a narrow sub-genre of pop music: Hit R&B/Rap Songs About Battling Supernatural/Extra-Terrestrial Beings. Another member of the category, Will Smith's "Men In Black," would climb the charts in August of 1997. The spiritual godfather of the genre, "Monster Mash," was a hit in 1962.
