hollow body guitar fed through an Edwards volume pedal to a Fender Bandmaster amp, all of which he had been given by Joe Walsh while in New York. This combination became his main electric guitar recording setup for subsequent albums. Although intended as a demo recording, the end result sounded so good to the band and Johns, they decided to use it as the final take. Overdubs, including an acoustic guitar part played by Townshend, were recorded at Olympic Studios at the end of April. The track was mixed at Island Studios by Johns on 28 May. After Lifehouse was abandoned as a project, Johns felt "Won't Get Fooled Again", along with other songs, were so good that they could simply be released as a standalone single album, which became Who's Next. This song is written in the key of A Mixolydian. Release "Won't Get Fooled Again" was first released in the UK as a single A-side on 25 June 1971, edited down to 3:35. It replaced "Behind Blue Eyes", which the group felt did not fit the Who's established musical style, as the choice of single. It was released in July in the US. The B-side, "I Don't Even Know Myself", was recorded at Eel Pie Studios in 1970 for a planned EP that was never released. The single reached No. 9 in the UK charts and No. 15 in the US. Initial publicity material showed an abandoned cover of Who's Next featuring Moon dressed in drag and brandishing a whip. The full-length version of the song appeared as the closing track of Who's Next, released in August in the US and 27 August in the UK, where it topped the album charts. "Won't Get Fooled Again" drew strong praise from critics, who were impressed that a synthesizer had managed to be integrated so successfully within a rock song. Who author Dave Marsh described singer Roger Daltrey's scream near the end of the track as "the greatest scream of a career filled with screams". Cash Box said of it that the song has "rousing magic with the Who's trademark instrumental and vocal strength" and that "revolutionary lyric matched by the group's performance fervor make this a monster on its way." Rock critic Paul Williams in a Rolling Stone issue, published on 17 September 1981, compared the instrumental built-up of the long version to the Doors' "Light My Fire". In
