Many of the editing and mixing decisions made for Anthology tracks were pretty bizarre. One of these was YKMN.

The version on Anthology is longer than the single version. But the mixers and editors LEFT OUT some "bits" from the single version  in making the long version. In other words, each version has bits the other doesn't! We still don't have a "complete" version.

Several complete versions are around, with the bits from the singe version edited into the Anthology version. Here is the best I've seen: simply click here, and the download will start.

This web site (a great site, by the way) has full details of each version of YKMN. Scroll down the page to get the link, or go directly there.

Do you know which Beatles are doing the 'fun' vocals on YKMN?

Yes.

ive never heard that song at all

It was the B-side of Let It Be but it can also be found on Past Masters Volume 2 and Anthology 3 - it's weird, odd, very funny and Paul McCartney's all-time favourite Beatles track!!!!

Who's doing the fun vocals then? Seems odd if it really is Macca's all-time fave Beatles track!

John and Paul shared the vocals.
Its not only Macca's all-time fave Beatles track, perhaps its mine too because it seems a demo track of a private party of my favourite band.

Its way too long and the vocals destroy it for me, but its just my opinion.
