Full-band audience karaoke should _totally_ be a thing

[andrewducker]

skreidle linked to the following video, showing a band _accidentally_ starting an audience sing-a-long of an AC/DC song:

"Matt Nathanson Aug 22, 2014: 15 - You Shook Me All Night Long [AC/DC] Impromptu-Clifton Park,NY Full" (Watch on YouTube)

And my reaction was "That's awesome! I want to go and see a band and have them play the songs while the audience sings them! Why doesn't this already exist?"

Singing songs as a group is great fun, but most singing groups tend to focus on either choral/classical/religious songs. And they tend to be doing it so that they can perform.

You don't get sing-a-long-a-rock. And you bloody well should!
