incarnation of Wings had demoed in July 1976. "Arrow Through Me", a track more in keeping with McCartney's melodic pop style, is a song written from the perspective of a rejected lover. With a musical arrangement that eschews guitar backing for synthesizer, Fender Rhodes piano and horns, Benitez views it as "reminiscent of the techno-pop style of Stevie Wonder". "Over Easy" Opening side two, "Rockestra Theme" was a composition that McCartney had first recorded in 1974, on the same piano demo tape as "Getting Closer". "Rockestra Theme" is an instrumental – except for the shouted line "Why haven't I had any dinner?", which author Robert Rodriguez describes as a "deliberate evocation" of Glenn Miller's 1940 single "Pennsylvania 6-5000". Another rock track, "To You" includes a lyric aimed at a lover who has wronged the singer. The guitar solo on the recording provides an unusual aspect for a Wings song, in that Juber played the part through an Eventide harmonizer while McCartney simultaneously altered the harmonizer's settings from the studio's control room. McCartney deemed the two gospel-influenced pieces making up "After the Ball/Million Miles" as being of insufficient quality to merit inclusion as separate tracks; "After the Ball" ends with a guitar solo, edited from parts played by McCartney, Laine and Juber, after which "Million Miles" consists of a performance by McCartney alone, on concertina. This is followed by another medley, "Winter Rose/Love Awake", both portions of which McCartney had demoed at Rude Studio, his home studio at Campbeltown, in 1977. "The Broadcast" is another instrumental, designed to give the impression of several radio signals interlaced, and bringing full-circle the concept established in the album's opening track, "Reception". Over a musical backing of piano, mellotron and gizmotron, it features readings taken from the plays The Sport of Kings by Ian Hay and The Little Man by John Galsworthy. As a return to the proposed working-band concept, "So Glad to See You Here", Rodriguez writes, "[evokes] the anticipation of a live act guaranteed to 'knock 'em dead'" and so recalls Wings' 1975–76 show-opening medley "Venus and Mars/Rock Show". During the outro, the band reprise a line from "We're Open Tonight". The album ends with a jazz-inflected ballad, "Baby's Request", which McCartney wrote for American vocal group the Mills Brothers, after seeing them perform in the South of France during the summer of 1978.
