But if you tune into BBC One on Saturday night, at 6.50pm, then Graham Norton will be able to help you solve the puzzle.

The wannabe Marias will slug it out on Saturday night
The auditions are now well under way, and Andrew Lloyd Webber is putting together his shortlist, determined that the part will go to a virtual unknown actress.

And Andrew Lloyd Webber's verdict on Susannah? She'd need two years' tuition, apparently.
