I'll kick it off - My favourite moment, apart from bokutachi on FL, and DS in general, is... this! µ's were meant to disband at that time, due to the 2nd season not being announced. This Live was right after the 1st season itself. The ending is just beautiful.
4:55 onwards - the transcript is below:
Arigatou and thank yous from seiyuu (hai x9 then crowd cheering)
Arigatou gozaimashita yo!
