^ Yeah, it already happened. You can download the audio at H!O
here.
Here's the setlist:
01. Happy Summer Wedding
Talk 1
02. Shabondama (Tsuji, with Ishikawa & Yoshizawa)
Talk 2
03. Mr. Moonlight ~Ai no Big Band~ (Yoshizawa, with Ishikawa & Tsuji)
Talk 3
04. SEXY BOY ~Soyokaze ni Yorisotte~ (Ishikawa, with Yoshizawa & Tsuji)
05. I WISH
I hope this gets released on DVD. I've always wanted to see a 4th gen version of I WISH, plus a Yossie solo version of Mr. Moonlight
and Tsuji singing Shabondama?!
The only problem I have is with Rika singing SEXY BOY. I just wish they had given her a better song, but oh well. =P
