The chorus of Staten Island’s PS22 performs a kind of astonishing version of “I’ll Be Your Mirror.”
Some songs you just want to hear performed by people so young that the lyrics make sense to them. Not just make sense but are experienced as startling truths encountered for the first time, and embraced. In this connection, see: the PS22 performances of Alphaville’s “Forever Young,” and “Don’t Stop Believing.” The latter, no lie, choked me up.
Quomodocumque 
That was sweet. I think choruses everywhere, not just at ps22, should sing good music. I hope all the attention they are getting starts inspiring elementary music school teachers to take more chances.
