In the annals of bizarro "Hallelujah" renditions, Wainwright led a chorus of 1,500 singers invited in June to a huge old generating station in Toronto as part of the Luminato Festival.
It was a Choir! Choir! Choir! session. What, you ask, is that? It's an open-participation choir in Toronto.
Anyhoo, there was Wainwright, who had done "Hallelujah" before, accompanied by an acoustic guitar, standing on a stage in front of the mass of choir people. Some wore little paper birthday hats and most held paper sheets of lyrics handed out.
The crowd swayed. They oohed at the right times, led by a choir director. It was strangely but compellingly epic.
