I’m not against remixes in general. It wouldn’t be done if Paul, Ringo, Yoko and Olivia didn’t approve it.
The Beatles were one of the first groups to push the envelope on what could be done in the studio, so it seems likely to me that they would still want to push that envelope.
Geoff Emerick, who was the engineer on many of The Beatles’ albums, says the guys were always pressing him to get different sounds for their songs, to the point where other engineers didn’t want to work with them because they weren’t happy if you couldn’t produce the sound they wanted. Oh, and they worked late and did marathon sessions too.
So, I’ll give it a listen and keep my copy of the original mix too.
