You know how annoyingly long the "Naaaaa na na NA NA NA NAAAAAA" ending of Hey Jude is when you listen to it on the radio or a CD? Well, it's definitely a whole different story when you're singing along with thousands of other Beatle fans.
Peter, as a long time performer, and having attended many concerts, I can tell you there are few things in life as magical as thousands of voices raised in unison, particularly if the song happens to be one you love. It's definitely a goosebump experience, and one that absolutely THRILLS most performers. Paul probably enjoyed it even more than you.
