I've seen him do the speech about carrying George in his pocket three times now, and it is the emotional high-point of the show on a narrative level, for me without a doubt.
I'd possibly say it was my moment of the night at Gothenburg #2 last year. I heard Racing in the Street for the first time there, but they butchered the outro and listening back, it was a bit of a mess. Conversely, the version at Wembley #1 this year was pretty much pinpoint perfect.
