This episode was the only one (other than the original pilot) with a different version of the theme song, which included female back-up singers harmonizing over the iconic slap-bass tune. The singers were added by composer Jonathan Wolff at the request of Jerry Seinfeld, who wanted to add “a little sparkle” to the music, suggesting the addition of some scat lyrics. Seinfeld and executive producer Larry David both liked Wolff’s additions, and three episodes were produced with the new style music. However, they had neglected to inform NBC and Castle Rock of the change, and when the season premiere aired, they were surprised and unimpressed, and requested that they return to the original style. The subsequent two episodes were redone, leaving this episode as the only one with the additional music elements. Also, since this episode’s credit music played “Joltin’ Joe Dimaggio”, this leaves the full version of the vocalists’ version of the song to be unknown.
