"One Less Bell to Answer/ A House is Not a Home" duet sheet music ?

This was sung originally by Barbara Streisand, written by Burt Bacharach, and most recently recorded for Glee. I REALLY want to perform this exact duet at my senior voice recital but I cannot seem to find a complete version on the internet. I can get the separate songs, but not the combined arrangement.

Please help me! Thank you!
