According to the old Beth's Days of Our Lives Page, it was used multiple times for Jack and Jennifer in 1991, so that would've been Matt Ashford playing Jack at the time. The Toni Braxton song, Un-break My Heart was used for Jack and Jennifer in 1997, which is when Mark Valley was playing Jack.
Wicked Game was also used once in September of 1990 for Nick and Eve. And an instrumental version only was used for Bo and Carly in 1991.
