 There is incidental music throughout the episode, which is not normally used on the show.It is one of only two episodes to be shot entirely on film (the other being "To Hull and Back" although, unlike that episode, The Nag's Head and Flat sets do not have an extra wall), only three without a laugh track (the others being "To Hull and Back" and "A Royal Flush"), one of three not to use the regular closing music (the others being "The Jolly Boys' Outing" and "Rodney Come Home") and the only episode not to use the regular opening titles and theme music, instead opting for a cover of The Lovin' Spoonful song "Summer in the City", recorded by the Gutter Brothers.The only on-screen mention of "Only Fools and Horses" in this episode appears on the first caption of the closing credits, only the "Miami Twice" name appears in the opening titles.
