At McCartney's suggestion, one of the versions had a brass band arrangement, anticipating his production of the Black Dyke Mills Band's instrumental "Thingumybob" in 1968. Turner writes that, given the film's setting in northern England, the use of a brass band in the Family Way soundtrack might have been part of McCartney's inspiration for the fictitious Sgt. Pepper band, which McCartney termed "a bit of a brass band, in a way".
McCartney proposed including a brass band arrangement in one version, which mirrored his later work on the Black Dyke Mills Band's instrumental "Thingumybob" in 1968. Turner posits that this could have been inspired by McCartney's idea for the fictitious Sgt. Pepper band, characterized as a "bit of a brass band."
