for Peter Gabriel or "Melt" and is described as an interlude. It references the experiment on obedience carried out by American social psychologist Stanley Milgram, intended as a reference to the obedience citizens show to dictators during times of war. Marotta's drums on the song – said to resemble "a heartbeat heard from the womb" – were coupled with Shankar's violin and "two overdubbed guitar tracks by Rhodes". While "We Do What We're Told" was the final song on initial LP versions of the album, the cassette and CD releases close with "This Is the Picture (Excellent Birds)", which Gabriel decided to include only forty-eight hours before the album's submission. "Excellent Birds" was composed with American musician Laurie Anderson. This was interpolated with a recording called "This Is the Picture", on which Nile Rodgers plays rhythm guitar. According to Anderson, she and Gabriel "could never agree on what a bassline was. (I think I probably don’t hear so well down there.) I wanted to learn from him, but it turned into a standoff and so we each put out our own version of the song." Her version, with Gabriel on additional vocals, appeared on her 1984 album Mister Heartbreak. Prior to the song's inclusion on So, Anderson and Gabriel performed it during the 1984 global satellite television broadcast Good Morning, Mr. Orwell. Release So is Gabriel's first non-eponymous album. Gabriel has noted his dislike for titling albums, mainly because it distracts from the sleeve design. In an interview for Rolling Stone, he explained that his American label Geffen Records refused to release Peter Gabriel IV until it was retitled Security. He elaborated that for So "[he] decided to go for the anti-title ... It can be more a piece of graphic, if you like, as opposed to something with meaning and intention. And that's what I've done ever since". When the album was profiled in the Classic Albums documentary series, Gabriel quipped that its short title meant it could be enlarged and useful when marketing it. Before the album was eventually named So, it was meant to be entitled Good. The album's cover is a portrait of Gabriel photographed by Trevor Key, who was then most famous for capturing the bell artwork for Mike Oldfield's Tubular Bells (1973). The sleeve was designed by Peter Saville and Brett Wickens; Saville was best known for designing several sleeves for Factory Records artists
