The MC is a caricature of Shocker Ohno, who was also the MC for the real life FURIL concerts. (BTW for those interested, you can read a report about the WP Festival event on Hitoshi Doi's site)

Performing as the band "Peach Angels" are, of course, Hinagiku Tamano/Angel Daisy, Momoko Hanasaki/Wedding Peach, and Yuri Tanima/Angel Lily.

Yuri's dad, Ryuuzou Tanima.

Momoko's dad, Shouichirou Hanasaki.

Providing backup vocals are the Love Angels' mothers... (Left to right) Elena Tanima, Sakura Hanasaki (Celeste), Akemi Tamano

And of course they couldn't leave the boys out of the fun. (Hey, what about Takuro?) (Back) Hinagiku's dad, Masahiro Tamano (Front) Yousuke Fuuma, Kazuya Yanagiba

There are two characters in the fifth row from the front, on the far right, that don't look human... but I don't recognize them from elsewhere in the series. :s
