Is it significant whether or not Beyonce lip synced the inaugural National Anthem?

Somebody says she did, somebody else says she did not. Perhaps she did, perhaps she did not. But what if she lip synced it? What would you think of that? I remember once there were these guys who got caught lip syncing a concert and got laughed out of town. One of them wound up killing himself (I think). So what would you think if you found out Beyonce was a fraud? Would you still think she was great. I used to think she was great. Now, I have doubts….
