I need some advice. I was just hired to perform for a Christmas Party for a large construction company here in Vegas. They informed me that the vast majority of their employees and dates do not speak English. Should I try to revise my act to be mostly silent to music? I have never worked in this situation before.

A friend of mine had this same situation happen to him...instead of changing his act he hired out me, since I do a Silent Show (FYI I can do up to 30 min. Silently). He came to the event and over-saw everything and made sure things went smoothly The event cordinator was impressed with both of us. My act and his attention to please the company, that he now gets booked for many of the english speaking events and he throws me the non-english ones...so we both come out ahead.
He was wise in my opinion because he stayed clear of possibly looking bad for a client for future events. hope this helps cheers chris
