Gavin Bain and Billy Boyd became Silibil’n’Brains.
They only got noticed by record execs when they dropped their Scottish accents for American ones. So they made up a whole American life and fooled everyone. Now they had to actually make a record to become famous, but if they did and it was released, they’d be revealed, and it would all come crashing down.

From an article in the Guardian>>

But the legacy of living a lie has not been easy for Bain, he will readily admit. Now that he’s no longer keeping a secret, he can’t stop wondering what everyone else must be hiding, and has trouble believing a word anyone says. "Once you know how easy it is, you think, why don’t people just lie all the time? Why wouldn’t they? It’s so easy when you do it – and then you get everything you want."
