A release date of 22 Sep 1978 is given in booklet 'The New Singles' No. 742
The Beatles’ 25th (official) British single, and the first to feature tracks from the Sgt. Pepper album.
In the summer of 1978 a Hollywood film, Sgt. Pepper’s Lonely Hearts Club Band, was released in the USA and led to a much renewed interest in The Beatles’ original album. The film, and accompanying soundtrack, featured Peter Frampton, The Bee Gees, Earth, Wind and Fire, Billy Preston, Alice Cooper, Aerosmith, George Burns, Frankie Howerd, Paul Nicholas and others.
Following Capitol’s lead (Sgt. Pepper’s was released as a 45 in the USA on 14 August 1978) and with the imminent arrival of the film on British screens, EMI released Sgt. Pepper’s as a 45 in the UK on 30 September 1978. It peaked at # 63 in the UK charts.
Interest in the original Beatles album prompted EMI to re-press it as a picture disc – Parlophone PHO 7027.
2nd issue: Black labels with EMI logo. Picture sleeve. Released 6 December 1982.
Uploaded are the Demo labels and the 1991 plastic moulded labels. the difference between 1978 and 1982, are not the label, the labels pretty much the same, but the pressing is done on a different machine.
