There's a version of this song in The Reliquary of English Song, which used to be a standard collection for young voice students to work from.

Anyone doing Shakespeare in college should consider going to the Music Dept. of the school and checking with the voice faculty there for sources for Shakespeare songs and coaching to help learn the necessary pieces.

Sorry. I've been out a bit, so just saw this thread. Hope I'm still in time to help someone.       Tw
