Quiz: Who played the stage roles first?

Musicals like Phantom, Importance of Being Earnest, Fiddler on the Roof or Mary Poppins may have passed into theatre legend, but the actors who originally played the roles may sometimes be a bit harder to remember!

So, in typical WhatsOnStage style, we thought we'd concoct a cheeky quiz asking you to name originators of some legendary roles (in either the UK or US!). Don't forget to let us know how you get on on Twitter or Facebook.
