The last note of the trumpet solo in Penny Lane
The percussion in Getting Better just before 'I used to be cruel...'
The 'oh' (Paul?)on the four of Taxman's counted intro.

The rocking intro to "Hey Bulldog"

I love this thread!!

Here's some I can think of:

The horn parts in For No One
The way John's uses his voice in ADITL. Especially the 'news' part. And of course the aaaahhh's.
The way John sounds when he sings 'row' in I Am the Walrus and 'happiness' in HIAWG and the last 'beautiful' in Dear Prudence. Talk about chills.
The guitar intro to Revolution and Paul's scream.
Paul's voice when he sings 'his rival it seems' and 'but Daniel was hot' in Rocky Racoon and the ahhs he adds at the end of corner and revival
The 'Like You' in Love Me Do
The intros to Eight Days a Week, I've Got a Feeling, Sgt. Pepper, and Baby, You're a Rich Man. Man I love the guitar intro to Sgt. Pepper.
The transition of Polythene Pam to She Came in Through the Bathroom Window. That aww look out part and so on is just so cool!
The oh, oh, ooo, yeah at the end of WMGGW.
The ending to I Am the Walrus. The way it builds up is sooo cool. And that chooba chooba thing. What is that?? It's just so cool.

And then I agree with sever already mentioned. The guitar solo in Let It Be as well as Paul's voice in it, Paul's backing vocals in I'm Only Sleeping and Ringo's drumming in ADITL to name a few.

Actually, the entire song Let It Be gives me the chills.  

Paul´s bass in Dear Prudence.

Mother Nature's Son very magical

Absouloutelly ... more than many acoustic they made by that time: Julia, Piggies, and many more ... it's one of my fab moments of the double one ...

Another moments ... begining of The Continuing Story Of Bungalow Bill... ending of  The Continuing Story Of Bungalow Bill and begining of While My Guitar Gently Weeps ...
That's not exactly Beach Boys Party! but ...

used to listen to the White one a lot over my earphones....always hated and still do the No9 rubbish - NOT magical

Across the Universe....magical

I used to listen to the double a lot and I like nNo 9 'cos it's crazy ... Do/Have you know/read the theories? ... some sites ...

Magical song? Dear Prudence is bea-util-full but Across The Universe is higher ... it's easy for me to agrre here 'cos this is one of my top-10 song ...

I love the percus-sion on Guys For Sale ... Every Little Thing for example ...

The Bass+Drums section on What You're Doing ...
