What is better for an audition, "Empty Chairs at Empty Tables", or "Bring Him Home" from les mis?

If you are a first tenor, "Bring Him Home" is probably your best bet- it will highlight your vocal talent in a way that "Empty Chairs" won't. Also, it's a better choice for vocal auditions= more musical, less busy/actor-y than "Empty Chairs". If you can really and actually get all of the range, than I would say that "Bring Him Home" done properly is a highly impressive audition piece for a 17 year old. Good luck!
