He was just going to bring them in for what sounds to be easy English assignment, sheesh. Aside from that, for an *English assignment*, it'd probably be advisable to have the official lyrics, not lyrics you copied from hearing the song- particularly a very lengthy, wordy, and complex song such as "Two Fairy Tales"... something that would be easily mistake-prone.
Though for future reference, the lyrics are printed in the published Night Music libretto... arguably an easier source than A Collector's Sondheim. Like the other Sondheim show librettos published by Applause, it contains a lovely appendix of cut material, production designs, etc.
"Didn't DESERVE to do the number." Geez.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
