Why is the Character Yitzak portrayed as a guy and played by a girl?
Stephen Trask wanted to have the high range back up vocals, and with a girl in the man’s role, this could easily be accomplished. Since Miriam Shor’s (original cast) portrayal it is now tradition to cast the part to a female. It’s also helps mess with the wonderful role of gender-bending on stage. Yitzak is a man, who used to be a drag queen (Hedwig made him promise never to wear another wig again once they got married) and dreams of becoming one once again.
