Re: total eclipse of the heart mass singing...
At confest, things are organic. No PAs or amped up sound systems. But some people like that sort of thing. Hmmm ... AHA! Silent disco. 50 sets of rechargable headphones, a short-range transmitter , a DJ set-up, voila!
Except, except, except that the people at the Silent Disco didn't get the "silent" memo. They sing along. Loudly. Usually badly. Sometimes everyone for a few hundred metres joins in. Bohemian Rhapsody gets them particularly enthusiastic.
