That's sadly the only one I've seen as well, though I've seen lots of clips from their other concerts (and their parts in H!P concerts are always the parts I look forward to most!
)
Same with me, actually xD I still have like, 3 songs on the Suiteroom album that I haven't heard (I'm waiting till I can buy the album or see them in concert before d/ling them)
Honestly, H!P needs another group that can really stand on its own and doesn't
a) rely on an anime for promotion and having a discography made up of OPs/EDs
b) have songs that can be interchangeable with EVERY OTHER H!P GROUP.
Basically, groups like Minimoni, Goto Maki, GAM, v-u-den, Melon Kinenbi, etc.
Sure Maki and v-u-den have songs that are performed by other H!P members (Yaruki! It's easy, Kacchoiize JAPAN!, etc.), but they had a distinct sound and could stand on their own without being confused with other groups (Well, I guess they COULD be, but the idiot who thinks SOME BOYS! TOUCH is a Berryz song and Aisu Kuriimu to my Purin is a C-ute song will be getting an epic FAIL tattoo'd on their forehead personally by me).
There's the new group, S/mileage, but I'm almost already sure their songs are gonna sound like C-ute/Berryz/Shugo Chara Egg. I'm so optimistic
This is why I wish High-King hadn't been just a oneshot thing.
