context: The movie features original music by Tom Hanks, Adam Schlesinger, Rick Elias, Scott Rogness, Mike Piccirillo, Gary Goetzman and Howard Shore. In the movie, The Wonders rise to brief stardom on the strength of "That Thing You Do", a song written as a wistful ballad but which becomes an uptempo rocker during the band's first performance at a talent show. Written and composed for the film by Adam Schlesinger, bassist for Fountains of Wayne and Ivy and released on the film's soundtrack, the song became a genuine hit for The Wonders in 1996 (the song peaked at #41 on the "Billboard" Hot 100, #22 on the Adult Contemporary charts, #18 on the Adult Top 40, and #24 on the Top 40 Mainstream charts). The track was nominated for a 1996 Golden Globe Award as well as a 1996 Academy Award for Best Original Song. Mike Viola of The Candy Butchers provided the lead vocals for the Wonders.
