Once Upon A Mattress Sheet Music

[Mr. B-Way]

Okay so my school is doing Once upon a mattress for our musical this year and we have the vocal score but we are looking 2 add the song "Good Night, Sweet Princess". But it is not in the original vocal score, it was added into the revival and we want 2 add that song ....so if anybody knows where i can find this i would greatly appreciate your feedback
