<P> "That Thing You Do" is a 1996 song that appears in the film That Thing You Do! The song is performed by the fictional 1960s band The Wonders, who are the focus of the film . </P> <P> In 1964, an Erie, Pennsylvania band named "The One - ders" (later known as The Wonders) goes from a college talent show to climbing up the Billboard charts thanks to the song "That Thing You Do". Written by guitarist / vocalist Jimmy Mattingly II, it was originally crafted as a ballad . During the performance at the talent show, drummer Guy Patterson produces a much more up - tempo beat and the rest of the band follow suit, turning the song into an upbeat, Beatles-esque rock number . The song is a hit with the audience, and they win the talent show . From there, the band is picked up by a local manager who helps them get more shows in the area, and eventually the song receives radio airplay . The band is then signed to Play - Tone Records, under Mr. White's guidance, and the song climbs up the Billboard Hot 100, starting at #93, then #71, #49, and #21 . The following week, "That Thing You Do" climbs to #7, becoming the quickest charting song ever on Play - Tone Records . However, Jimmy walks out on the band before they can produce another record, so they eventually become one - hit wonders . </P> <P> Early in the film, when Jimmy and Lenny are asking Guy to join them at the talent competition at the college, Jimmy mentions they'll perform a song he wrote . Lenny takes offense to that by slapping Jimmy on the arm . Jimmy begrudgingly corrects himself by saying, "We wrote ." Later, when the vinyl 45 is officially released, the label states: Written by James Mattingly II . Later still, when being interviewed live on radio station KJZZ, Jimmy says of the song, "We wrote it in my garage back in Erie, PA". </P> <P> In the film, the song is performed by James "Jimmy" Mattingly II on lead vocals and guitar, Leonard "Lenny" Haise on lead guitar and backing vocals, "T.B. Player" on bass and backing vocals (as a running gag, the bass player in the film is unnamed), and Guy "Shades" Patterson on drums . For their live performance of the song on The Hollywood Television Showcase, studio bassist Scott "Wolfman" Pell replaced T.B. Player on bass and backing vocals . </P>
