John: your normally stoic man is quaking like you've never seen before, at least from him. His fingers are trembling and he stumbles over the words in his vows. It melts your heart to know that this means so much to him.

Paul: he is grinning like a banchee the whole time, unable to take his eyes off of you. He's so mesmerized and frankly distracted by you that it takes him a second to realize that its time to kiss the bride

George: he doesn't realize that he's getting married until you're right in front of him, and he starts crying when he finally does. He sniffles a little bit through his vows but keeps it pretty well together

Ringo: all he does is smile at you, and when he isn't smiling, he's speaking quietly. He stutters a little and his palms are sweaty, and when it's time to kiss you, he misses your lips entirely.
