Also btw Vocaloid mascots aren't real, so how can their derivatives cry? Well, believe it or not, some people actually think the Vocaloids, and their derivatives, are real people (I'm not making this up). We believe you, some of us have seen it. Some think Miku is just a place holder for her provider, there are those who think Vocaloid is a band, game, anime...Then those who don't believe Gumi is a Vocaloid and is instead of a "Megppoid", Kaito has a last name and its "Shion".

So many, many things...

As for the concept, I've seen no official ads, therefore there is limited proof. You cannot have a cncert without asking the owners for premission to use the characters.
