World Purple Rain Hour

This is World Purple Rain Hour

On the 21st Dec 2012, at precisely 12am UTC the world will greet its end by blasting out Purple Rain together in unison.

It's just like Earth Hour, only far sexier. If the world doesn't end, maternity wards will be overflowing in nine months time.
