Tom Waits' gruff, whiskey-soaked growl became the focus of a lawsuit that the singer filed against Frito-Lay in 1988, when the corn chip producer, unable to secure permission from Waits to use his tune 'Step Right Up' in a commercial, instead hired a voice impersonator to sing a soundalike jingle.

Waits, who has fiercely fought against such use of his music in commercials several times since, became one of the first artists to successfully sue a company for using an impersonator without permission -- and he cashed in big, as the jury awarded $2.375 million.
