You're the One - Gene Taylor

Intimidated by the clubs and cabarets of 1970s Chicago, shy English teacher Graham Thomas needs a miracle just to be able to talk to a man. When help arrives from a Robert Redford look-alike wizard, Graham brushes him off-he's obviously certifiable. Or so Graham thinks until he tries out a popular song title as a come-on line and everything changes.
Given the power to make others fall in love with him, Graham begins to enjoy the nightlife. But when he misuses his gift, he finds himself with accidental and unwanted suitors, including the senior dean at his school, a ticket-mad cop, and a rich young banker. Then Graham meets Mark Matthews and finally faces the moral issue of whether it's fair to use magic to make someone fall in love. It would be so easy... .
