The first task was to create a reduction mix to allow more overdubs to be added. Harrison double-tracked his lead vocals, after which a second reduction mix - numbered take three - was made.
Harrison, John Lennon and Paul McCartney then added some backing vocals onto track three. These were put through a Hammond organ's Leslie speaker to give a swirling effect. Track four was left empty for now.
This session began at 7pm and continued until 3.15am on the morning of 8 September. Recording for Blue Jay Way was concluded on 6 October 1967.
