We were singing Yeish Kochavim (There are Stars): poem by Hannah Szenes, music by Jeff Klepper; you can hear it here by Elana Jagoda.
"There are stars up above,
so far away we only see their light
long, long after the star itself is gone.
And so it is with people that we loved.
Their memories keep shining ever brightly
though their time with us is done."
Thankfully, in my choir, tears are lovingly accepted...even in performance.
