Would "Sgt. Pepper's" be a better album if.....

I'll bet Ringo wishes all The Beatles albums would be remixed. When he heard the first album, his response was "Where's me kick?'. George Martin was not a Rock 'n' Roll producer, and put Ringo's bass drum waaay down in the mix, giving them a more "Pop" sound than they imo should have had . The Beatles started as a Rock 'n' Roll band, and turned into a Pop group. A rather good one ;-).

" Would "Sgt. Pepper's" be a better album if..... "

well, its not going to happen, so guess it really doesnt matter now does it?

Different Agoners would keep or cut different tunes.  There's no absolute answer, no consensus, on this.  If you put SFF and PL on this LP then what happens to the Magical Mystery Tour LP (without those two very strong tracks)? 
When I'm 64 is a fairly lightweight song (he wrote it when he was 16) but IMO they managed to make a good track of it.  And it is very popular.

Honestly, they would have been better off not doing MMT and gone on to the White Album.  MMT is the weakest album of their discography.  I'd almost say it was an album they released to satisfy the bean counters at Capitol, etc...

I think the 50th anniversary edition of Sgt. Pepper's that Giles Martin  produced was released earlier this year. Here are details, https://www.beatlesbible.com/2017/04/05/beatles-sgt-pepper-50th-anniversary-edition/

I believe you can stream Giles' version of Sgt. Pepper using TIDAL Look for the album artwork with the word 'DELUXE EDITION' on the left hand side. It's noticeably better sounding than any other Redbook CD versions I've heard and miles ahead of the mono CD version that sounds lifeless.

 With all due respect to the hypothetical question you posit here,  with my full disclosure that my intention is by no means to denigrate let me ask the rhetorical question if I may:  given that Sergeant Pepper is largely regarded by most all legitimate rock 'n' roll historians and critics as the greatest album of all time and largely "perfect,"  why would anyone even attempt to suggest that one could improve on perfection and or the greatest albums of all time? Why not let "sleeping beauties" lie and appreciate what you've got? :-) 

saintintn, I think MMT is far stronger than Beatles For Sale, which is such a disappointment coming after the very strong A Hard Day's Night album.  I do agree with George Martin that "the White Album" should have been a single disc and not two.  That's the one (of the later ones) with a lot of filler.

And, the OP begs the question:  Would Revolver be a better album with Rain and Paperback Writer instead of I Want to Tell You, Dr. Robert or Love You To?
These guys knew what they were doing.  They dropped songs or re-did them from scratch when they felt the quality was not there.  I trust their judgment.  SPLHCB is just fine as is.

I have to admit that I have not listened to the new mix yet, but I find it hard to believe that anyone would want to change the tracks. Personally, I could see making the drums louder or even reducing the reverb and EQ effects on the vocals. But the album stands up pretty well after 50 years.

Like many people, I was disappointed at the time that the radio hits,  Penny Lane and Strawberry Fields weren't on it. But after one listen, I didn't miss them at all. I was perfectly content to buy the 45 separately - which is what they wanted you to do.

Despite the chatter at the time,  this is not a "psychedelic" record. Oh sure, it has a thin veneer of sound effects and unusual instrumentation spread across it, but it really is a British work - romantic ballads, skiffle songs and dancehall music with American rock clichés almost completely stripped out, perhaps the most British that they ever sounded.

I like it just the way it is. 

The one song I'm disappointed that never made it onto Sgt.Pepper is Only a Northern Song which is a great psychedelic Harrison tune.  

I'm going to stand up for Ringo as always providing a nice musical break.My favorites include "An Octopus's Garden" and "Goodnight"

I like Ringo's second album, Beaucoups of Blues (recorded in Nashville with the cream of that city's session players), and his third s/t one. He's not much of a singer, but then neither is Mick Jagger. He's certainly far better than was Lou Reed!
