I wondered if that was Paul, HG.  I'll have to look at that video.  Pretty awesome scream.  

Roger Waters on "Careful With That Axe, Eugene".

I think the 'Revolution' scream is both Paul and John, but i'm not sure.

I think you're right, it's a harmonically blended scream (if that's possible).  I'm not sure if it's a scream but Van Morrison does some guttural pyrotechnics on "Listen to the Lion."

And the worst one? Paul's on Golden Slumbers: Smileeees awake you when you rise...
Ouch!

I always wondered why he was screaming a "lullaby."   Poor kid musta been frightened to death.

That's one of my favourite parts to that song. He sounds very emotional.

Would you call that a scream? Surely he's just putting in some heart felt emphasis. And it sounds great.
I think it was quite clever to put a roar of adult emotion into lullaby lyrics - it lifts the whole song.
If you're having that then I'm having John's girlie ye-he-hee on Imagine

John has similar (ye-he-hee) scream (or whatever you call that) on Don't let me down - but that one is nice, isn't it?
Screaming for Yoko, I suppose...

Maybe to WAKE UP somebody with this lullaby...
(Smileeees awake you when you rise...)

Woke up, got out of bed ...

Back to best screams...
How about Paul's collection of screaming and shouts on refrain of Hey Jude???

(http://www.pootle.demon.co.uk/wgo.htm)
...the full text of Paul’s amazing shoutings from where it comes in clearly at 3:58 is (approximately) …

(3:5"Jude Judy Judy Judy Judy Judy.. ow, wahow!"
(4:07) "Ow hoo, my my my"
(4:12) "Jude Jude Jude Jude Joo-oo ..."
(4:1"Na na na na na, yeh yeh yeh"
(4:24) "Yeah you know you can make it, yeah Jude, you not gotta break it"
(4:30) "Don’t take it bad Jude"
(4:33) "Take a sad song and make it better"
(4:36) "Oh Jude, Jude, Hey Jude, woooow"
(4:44) "Ooo, Joooode"
(4:47) "Yeah"
(4:50) "Hey, hey, hey-ya-ay"
(4:57) "Hey, hey, hey …"
(5:03)"Now Jude Jude Jude Jude Jude Jude, yeah yeah yeah yeah …"
(5:12) "Woh yeah ye-ah"
(5:16) "Ah nanananananana cause I wanna na na na"
(5:20) "Nanananana ... nanalalal ow ow ow"
(5:35) "Oh God"
(5:37) "The pain won’t come back Jude"

(5:5"Yeah, eh hehe heh"

(6:41) "ooo"
(6:47) "Woooh"
(6:4 "Well then a na-nanan"
(6:56) "Isn’t that …"

And the song starts sooo soooftly...

And how about John's  (aaaaaahs) on "A Day In The Life" (after Paul's "Somebody spoke and I went into a dream.")???

"It's beautiful and so are you..."

Paul's Helter Skelter?
And Ringo's (at the end of the song): I've got blisters on my fingers!"

There's a lot to say about this particular subject   ...

Sometimes I hate Lennon's screams. He sounds extremely crazy...
