John Vanderslice posted this on his Tumblr today and I thought it was very interesting. Have a listen and also check out his notes.
Beatles - A Day In The Life (Lead Vocal Track)
Interesting things:
-There’s an incredible amount of headphone bleed
- Sounds like Lennon and McCartney are sharing the same vocal booth
- Piano is shared with main vocal track (:55. 1:10)
- Fantastic sounding tape delay in countdown (1:50) and last verse (3:20)
- JL hums along with PM (2:42)
- I think you can hear Lennon laugh around 2:48
- Beautiful artifacts of linear recording (3:19)
- “A Day In The Life” was recorded on a 4-track Studer J37.
