Somebody on youtube uploaded 3 videos (though low-quality) of 3 performances that didn't make the cut onto the DVD! Koko de Kiss Shite, Yattsuke Shigoto, & Gamble! I'm so happy

I can tell this performance of Gamble is the same as what's on the ZCS disk, but I'm not sure about the Yattsuke Shigoto one.
