I listened to the midi files that leeneia linked to, and noted that they were a quite a bit faster than the melody should go. Also, in the first phrase, the word "grow" is not on just one note, or an octave jump, as it sounds. It calls for a full octave scale on the word "grow." Not easy, but it's one of the salient parts of the song.

I combed through videos on YouTube for a good example of the song being sung. There are a lot of them there, mostly pretty badly sung or acoustically not good. Countertenor Alfred Deller is represented there, but his rendition is so idiosyncratic that I can't recommend it.

This young lady isn't yet up there with Anna Netrebko, Kiri Ti Kanawa, but she sings it about as well as anyone on YouTube, and better than most.

CLICKY.

By the way, speaking of Anna Netrebko, if you're one of those who think all operatic sopranos are built like whales, take a good long look at Anna.    Whooeey!!!!
