Brazen it out, Roger -- make them think it's supposed to sound like that! They'll think you're some unknown avant-guard performer, or an undiscovered "primitive" artiste, and you'll go down a storm. If no-one knows how they are expected to react, they may wait for someone else to give them guidance, so rely on Sam to make you famous (or better still, prime him so he knows what to do!)

We're gonna make you a sta-a-a-ar!
