So, I learned today that Hugh Laurie (of House and Jeeves and Wooster fame) has not one, but two blues albums out (you can read more details here: http://didntitrain.hughlaurieblues.com/us). Today I am also supposed to be working on my next English-language display, and this gave me the idea for a "I didn't know he did a _____!" display. I.e., "I didn't know Hugh Laurie did a...blues album!"
But I have a problem. I am struggling to find lists or examples of celebrities (actors, writers, etc.) who are famous for (or at least did) more than one thing. Any suggestions, off the tops of your culturally-literate heads?
