American radio stations interrupted their regular scheduling, playing the album virtually non-stop, often from start to finish. Emphasising its identity as a self-contained work, none of the songs were issued as singles at the time or available on spin-off EPs. Instead, the Beatles released "All You Need Is Love" as a single in July, after performing the song on the "Our World" satellite broadcast on 25 June before an audience estimated at 400 million. According to sociomusicologist Simon Frith, the international broadcast served to confirm "the Beatles' evangelical role" amid the public's embrace of "Sgt. Pepper". In the UK, "Our World" also quelled the furore that followed McCartney's repeated admission in mid June that he had taken LSD. In Norman's description, this admission was indicative of how "invulnerable" McCartney felt after "Sgt. Pepper"; it made the band's drug-taking public knowledge and confirmed the link between the album and drugs.
