Along with electric bass, I used French harpsichord E and the Mellotron cello sound on my Nord Electro 5. I'd learned just the beginning phrase of the harpsichord part in November 2017, but I never wrote it down. I recently re-learned it and then got a bit more too. I noticed what is probably a trivial feature in the second phrase (at ~0:21):
The last four notes of the first measure have the same intervals as the third phrase of "Westminster Quarters."
This is probably just coincidental, but I thought I'd point it out all the same. (For what it's worth, Paul McCartney also quotes "Westminster Quarters" at the beginning of his "Let 'Em In.")
