????? - I haven't even figured out what you're talking about. If you're referring to Rhianna, all of these type shows are produced this way. Nothing could be further from the amateur/semi-pro world of the solo Arranger player playing a nursing home than a billionaire superstar playing to 100,000,000 (check Google) people at the Superbowl. I don't think she has to prove anything to anybody. The point is, there is no DECEPTION here, perceived or real.

One way to show your audience that you aren't just 'faking it', is to sit down at that ever-present acoustic piano that's ALWAYS in the nursing home's entertainment space, and play a short vocal-less medley of songs (show tunes or classical or a mix). After that, you can move over to your trusty arranger with no concerns about the audience's perception.....OR, just stay on the acoustic piano (no gear, no setup, no tear down). Same money.
