The Beatles "Help / I'm Down" single (2024 spectral remix)

I have used spectral demix technology to pull apart the old stereo mixes into separate discrete audio stems (drums, bass, vocal, guitars) for remixing. The drums are now in the center for the first time. On "Help!" the lead guitar has been flown in from the pre-bounced take. On "I'm Down" the "..down" backing vocals are now in wide stereo and the song has been extended using a demix of the mono version which was longer.
