Opera coming from PS9?

did anyone else hear snippets of opera singing coming from P.S.9 last night around 7-7:30? I live right across the street and heard a deep, male voice singing a line or two (something like "ave maria...") a couple of times during the evening--it wasn't very loud, so I thought I'd imagined it at first, but then I heard it couple more times...

I'm no opera afficionado, so I'm not sure if this was a recording/broadcast or just a spectacularly talented PS9 staff member, but it certainly was a nice surprise.

Phantom deep-voiced opera man, if you're out there, I salute you!

i think i saw this guy walking down the street, at the corner of prospect and underhill around 7:30. if it's the same guy, he was just singing to himself. very beautifully.
