I should warn you Madara, the live house joint group tours are not like the regular tours, despite one or two songs the groups share together, they don't sing or do any shuffling of members. Pretty big let downs if you ask me. And a wasted opportunity!
I have to agree with this. I just recently watched Sorezo-re and Mazeko-ze concerts, and while Sorezo-re (just one group at a time) bored me to tears, I LOVED mazeko-ze(shuffles) and haven't even deleted it yet.
