A pro by virtue of getting paid maybe? Sorry, maybe it's more typical of female impersonator shows in general,  but it's definitely not in the same league as the La Cage show in Vegas.  
La Cage was a class act with tons of talent and no lip syncing .. and no dollar bills.  The guy who impersonated Cher was especially amazing, and we decided the mistress of ceremonies was better at being "Joan Rivers" than the real one.  Understand it's back after a couple years off, give it a try if you go to Vegas.
