Music From Twelfth Night

[Laura Roald]

I am currently hunting information on the music of Twelfth Night
for an upcoming production at Bishop's.  Any info on original
music (including recordings, sheet music or MIDI links) as well as
music composed for the show in any period/place of production would
be a big help, as would research hints (online and otherwise).
 It would also be great to hear about the pieces chosen for other 12th Night
productions.

Thanks!
