Very!
Toshi couldn't get his voice right due to the cry for more than half of the song! It's very moving. And yes, I saw Pata's expression.. well he looked very moved and emotional not only in this song, but most of them in these 3 day concerts.
Pata showed more smiles and sadness, and also more interactions with other members esp Toshi than usual. =p
This reunion really a shock gift for all of them.
