I have an appointment for an audition for Fiddler on the Roof coming up, and I can't decide whether to sing "Waitin' for my Dearie" (Brigadoon), or "What's the Use of Wondrin'" (Carousel). Would it be acceptable if I offered both and let the casting director CHOOSE the piece he wanted to hear? I've always thought it would be neat to let them decide, and I know this is ok in opera auditions, but I didn't know if it would be right for musical theatre.
I do not think you should ask the casting director or director what song they would prefer. I think you should come in with your song choice and if they ask, "What will you be singing for us," then you could possibly say, "I have ___ and ____, which would you prefer to hear." Most of the time, though, they just want singers to come in, do your business with the pianist, sing, and leave.
I think you should choose a song that has the same passion and longing as "Far From The Home I Love," from Fiddler.
