Sing for Gaza

Just saw the Alcazar sings for the children of Gaza and it is nice. In this case, I know nothing at all. Do not know where it is, when it does, and so on.

Usually when I hear artists sing for "charity" which happens quite often, it is sometimes for the homeless, it is sometimes for accident victims, etc.. Unfortunately, like I was not really the way it is. In most cases it is so that there is any artist who plays either a concert or a disc. The idea is GOOD ..  What I do not like is that we are "ordinary people" that will pay for example, the disc recording.
