The thing is though, I haven't seen too many where people do a flash mob with live singing. The ones I have seen usually have 100s of people singing. (such as the Hallelujah chorus in Kansas City, where my Aunt participated)
Plus it usually doesn't get the attention that a recording does. (and you would have to get people that can sing well) Unless, of course, you have hundreds of people.
I don't even know what a "flash mob" is. Can anyone explain this phenomenon to me? And what this whole thing is about?
Honestly, as a COMPLETE outsider, the whole thing looks totally contrived to me.
A flash mob is when a group of people decide to meet in a single place for some sort of event or cause. Usually no one else knows about it. Oftentimes it will be a mass occurrence.
Sometimes flash mobs are organized by a random group of people and sometimes they are organized by companies for advertisements.
Some flash mobs are singing songs, some are dancing... I've seen others that are ninja battles, frozen crowds etc...
