Hi, welcome to the forum.
I think the best source for "I Feel Fine" is this one...
It starts with takes 1 and 2, which are both breakdowns. Take 1 is in a higher key, but take 2 sounds like the regular key. Next are takes 5 and 6, which are both nice complete runthroughs. Take 6 has no singing. Then there's an announcement for take 7, but it isn't available. Finally, the finished take 9 is presented in a different mix and without the fadeout, so you can hear the band breakdown at the end.
The regular mono mix of the song is also a little different, it's on that official "singles" collection if you can find it.
