Recent BR concert story: I can't top February 14, 2008, in Ottawa, where Greg told off a loud drunk guy who was yelling all the time. Copy-pasted from the review thread:
There were some drunken louts yelling things (you know, "YEAH
KEELOR!!!", stuff like that) during songs like "Know Where You
Go"/"Tell Me Your Dream" and "Dark Angel", prompting Greg to tell this
anecdote:
He had gone to see Neil Young at Massey Hall, and there
was this guy sitting beside him (Greg) who kept yelling out "NEIL!!!!"
during really quiet bits. Greg wondered what was going through Neil's
mind when he heard that. "And now I know!" Greg said. "He was thinking,
'What a f*cking A-S-Shole!'" Ha ha! Hooray for Greg! 
It was a treat to be in the front row for that little gem, let me tell you. 
DTPBM like to record stuff on the computer? Sooooo much fun, especially when you're sleep-deprived and just saying whatever pops into your head. 
"There's the shirt that I like!"
"It was nice singing with you this evening."
