Album: The White Album – released November 22nd, 1968
“While John was busy experimenting with sounds, Paul started and finished the recording of ‘Blackbird’, a lovely new composition which featured his own lead vocal, double-tracked in places via an overdub, accompanied by his acoustic guitar and a metronome gently ticking away in the background. It was a straightforward recording – no reductions necessary – and was perfected by the 32nd run through, just 11 of which were complete.
There was one other addition to the four-track tape: chirruping blackbirds, courtesy of “Volume Seven: Birds of Feather”, from the Abbey Road taped sound effects collection, the doors of the trusty green cabinet already being open during this evening for raidings by John Lennon. “I taped that on one of the first portable EMI tape-recorders, in my back garden in Ickenham, about 1965,” recalls Stuart Eltham.
“There are two recordings, one of the bird singing, the other making an alarm sound when I startled it.” Six mono remixes of the song were made before the session in studio two ended, the sixth being ‘best’.”
