I went to a RedMan concert when I was in college and I remember a guy that signed the entire show. The interpreter looked exactly like Santa Clause—so just imagine a old white guy with white hair and a white beard signing along to RedMan. A part of me thought it was total fake, but there were actually a huge number of deaf kids there. They even had a light show that was synchronized to the performance.
Anyway, it’s kind of sad to see someone fake sign language.
