Some big Tv and music stars have done some commercials. And some even have done radio ads. Sometimes I can't tell who the big name person is, until after I have read about it or been told who it is, but there are a few big time people out there who are very distinguishable by their voice. I can think of 3 popular people who I can recognize immediately when listening to their voice. They are Sean Connery, Sam Elliott and Jack Black. Can you think of any others?
