The song that Felix was singing throughout the episode is an original composition made specifically for this episode. It was created through a close collaboration between writer Michael Angeli, director Wayne Rose, actor Alessandro Juliani, and Bear McCreary. Here is Bear McCreary discussing its connection and importance to the episode itself.
And here’s a quote from Michael Angeli concerning how the song evolved after finding out that Alessandro had studied Opera
Heres a copy of the lyrics that were written for it
* Alone she sleeps in the shirt of man
* With my three wishes clutched in her hand
* The first that she be spared the pain
* That comes from a dark and laughing rain
* When she finds love may it always stay true
* This I beg for the second wish I made too
* But wish no more
* My life you can take
* To have her please just one day wake
Tomorrow I’ll go back through the episode and make sure these are correct word for word, but for now they should be satisfactory as they’re straight from Bear McCreary’s blog
I think it’s pretty interesting to see how important the music made for this show has become to the show itself(a testament to its quality), this is the first time Bear’s music has been so directly involved, down to the script level, with an episode and he also says that it won’t be the last time.
All information in this post is prettymuch brought over directly from Bear McCreary’s blog(http://www.bearmccreary.com/blog/?p=349#more-349), I thought you guys would be interested in seeing how this unique piece came about and what it meant.
P.S. oh and also, The Stump Serenade is the name that Alessandro came up with for this piece =)
