A longtime guilty pleasure of mine, made all the guiltier by this clip from the film (?) Fireball Jungle:
Mercy, "Love Can Make You Happy"
indeed, a cheapie race-car flick from '69. This from a review on IMDB:
"The film features the oldies warhorse, "Love Can Make You Happy" by Mercy (billed here as The Mercy Group). When I knocked around Tampa/St Pete in '92(?), the Sunday paper ran a puff piece on the composer. As the story goes, the film's producer drafted his teenage son to concoct a love song...a queer notion, given that hardly a smooch is exchanged in what amounts to 90 minutes of antisocial behavior. At the time of the article, the song still earned him five-figures in annual royalties, as he fronted a lounge band, dreaming of a comeback."
