Who - Acapella - where from?

[_dandy_]

Does anybody know what this version of Who is from?

Just hit the Play button - The Download button results in popups and redirection-galore, and fake virus warnings (sorry about that - I have no affiliation with the site, and would have posted an alternate link if I had one).

I think it's a jaw-droppingly magnificient version of the song - it's too bad it's so short.

And more importantly - is the live concert this is from available anywhere? I've probably seen all the CDL/AT concerts, but I don't recall ever seeing this.

Thanks.
