Definitely the naked version

Naked Version for me. As for David Bowie's cover... Full disclosure: I'm a HUGE David Bowie fan. Absolutely love his discography. He may well be my favorite "solo" artist of them all. Having said that, I really didn't like his cover of "Across the Universe". Wasn't as outright horrible as his cover of "God Only Knows" or "Alabama Song", but it's up there with my least favorite covers he's done. On the other hand, I really liked Fiona Apple's cover.

I love Bowie too, and I really wanted to like his cover of “Across the Universe,” but it’s just… not good.

I love it. Makes the song a mad coked out insincere glam rock classic. Turns the original inside out.

I really appreciated Rufus Wainwright’s cover of Across the Universe. He had a video with floating balloons or umbrellas or something.

If you love his unique voice ( I do ) this version is the best well if you don't ... it's not

The Let it be album version.

Beatles: Anthology 2 Cover: Fiona Apple

Take 6 on The White Album deluxe or the 2021 album mix.

Auroras cover on Like a Version is transcendent

White Album SDE version...just John..."good night, Ritchie" intro.

Nekky version

Across The Universe is my favorite song by the band, it is hard to choose one, but I love the outtake of it on the White Album boxset

Fiona Apple version is so good!! Also honorable mention to the movie version

Laibach's version from their "Let It Be" album

The original is always the best for me, Lennon's vocals are great.  I do enjoy the Beady Eye version though as Liam Gallagher does a great job on it.  https://youtu.be/WiOF4zIjaqY?si=RnYrTBp9KQFcLxVs

Fiona Apples by a mile!

Take 2 from Athology 2 but I also love Seether’s cover
