Short answers, pulled from the story.
1967-1970, commonly called the Blue Album, is a double LP compilation of Beatles recordings released in April 1973 alongside its companion 1962-1966. It was produced by Apple and EMI/Capitol Records and covers songs from the years indicated in its title.
The Blue Album was released in response to an unauthorized bootleg collection called Alpha Omega, which had been sold on television the previous year. Apple Records manager Allen Klein ordered both official compilations during his final months in that role. Print advertising for the records declared them 'the only collection of the Beatles.'
On its original 1973 release, 1967-1970 topped the Billboard albums chart in the United States and peaked at number 2 on the UK Albums Chart. By the 31st of December 1973, it had sold 1,294,896 copies in the United States. By the end of that decade, US sales had reached 5,850,026.
Six singles appearing on 1967-1970 were making their global album debut, including 'Strawberry Fields Forever,' 'Penny Lane,' 'Hey Jude,' 'Lady Madonna,' and 'The Ballad of John and Yoko.' The B-sides 'I Am the Walrus,' 'Revolution,' 'Don't Let Me Down,' and 'Old Brown Shoe' also appeared on an official album for the first time on this compilation.
The deluxe expanded edition released on the 10th of November 2023 added nine tracks to the compilation, including 'Now and Then,' described as the final original single by the Beatles. Six tracks received entirely new stereo mixes for the release, and the edition was made available in Dolby Atmos surround sound.
'The Ballad of John and Yoko' was absent from the Spanish edition of 1967-1970, replaced by 'One After 909.' The song had been banned from Spanish radio airwaves after its 1969 single release due to lyrical references to 'Christ' and 'Gibraltar.'
The album cover was designed by Tom Wilkes. The cover photograph combined an image from a 1969 session by photographer Angus McBean with an unused frame from McBean's 1963 session for Please Please Me. The inner gatefold came from the 'Mad Day Out' session of Sunday the 28th of July 1968, with credit attributed to both Stephen Goldblatt and Don McCullin.
