Brian was cracking the "how loud can you yell" comment for a good few years after that 2000 show you saw. Same with "Row Your Boat" and "Cigarette Lighter" joke. Not really a good way to judge how spontaneous or into a gig Brian is. As for most artists their studio vocals will usually be better, especially as the use of auto tune has increased in recent years. Maybe this is why Brian's studio vocals are better. His voice was stronger 10 years ago naturally. However he was more 'shouty' back in the 80s and 90s and definitely 'sings' more now. He's been up and down vocally over the years since I first saw him in 2002. Pet Sounds Tour 2002, Smile in 2004 and Gershwin and TLOS when he did the new stuff all very good. Greatest Hits stuff not so very good! Studio wise I love "Little Baby Mine" on the Disney album. Fabulous vocal.

I'm sure the "how loud can you yell?" was a common bit, but I was at the show; he was uncommonly upbeat and jovial, and very loose and comfortable (I've seen around ten Brian shows in person and heard I'm sure dozens and dozens of recordings), hence the funny f-bomb. The recording just re-reminded me of how unique the show was. A real treat. One of the only times I've seen him live where I could say unequivocally that he was fully enjoying doing the show.
