Anyone know why Trick Or Treat (1986) (which stars Gene Simmons and Ozzy Osbourne) didn't have a single track by either artist on the soundtrack? And why they chose Fastway (of all bands) to do the majority of it? I'm fairly confident that had a lot to do with its financial failure, but I'm just curious if anyone knows what De Laurentiis was thinking by doing that? I don't ever recall them being overly popular or "up-and-coming".
After critical and commercial success, the band toured to promote the album (with one-time Fixx bassist Alfie Agius as their session bass player). The band then recruited Charlie McCracken, formerly of Taste, as "permanent" bassist, and released another success in the form of All Fired Up the following year. After the hardships of touring, Shirley and McCracken subsequently left.After critical and commercial success, the band toured to promote the album
So they could have been seen as an 'up and coming' band during 1986. That could've been the reason why they were approached for the movie.
Secondly, in the same article on Wikipedia, they mention that
Fastway was approached to make the soundtrack for the heavy metal horror film, Trick or Treat. The film flopped, but the soundtrack re-established Fastway as a hard-hitting metal band. The soundtrack was a moderate success, and stayed on the Billboard Top 200 chart for eleven months.
So may be Fastway was not solely responsible for the movie's commercial failure.
