Final answer:
The Beatles' last time together in the studio was on August 20, 1969, for the album Abbey Road. The correct answer to the quiz is b) Let It Be; "The Long and Winding Road", but it's a bit misleading as this song was recorded before their final session for Abbey Road.
Step-by-step explanation:
The last time the Beatles were together in the studio was on August 20, 1969, during the recording of their album Abbey Road. Option a) Abbey Road; "Come Together" is incorrect because "Come Together" was one of the earlier tracks recorded for the album.
The correct answer is b) Let It Be; "The Long and Winding Road", although this answer can be a bit misleading. The Beatles' last recording sessions were for the Abbey Road album, but the Let It Be album, which includes "The Long and Winding Road", was released later; it had been recorded earlier. The last songs the Beatles recorded together for the Abbey Road album were "I Want You (She's So Heavy)" and the 'medley' on Side 2 of the album, and the last session in which all four members participated was for "I Want You (She's So Heavy)" on August 20, 1969.
