Someone really needs to brush up on their research.

You would think that starring in a modern movie musical would make you swot up on your musical history but apparently that's not the case when it comes to Ryan Gosling and Emma Stone. Britain's Magic FM decided to quiz the 'La La Land' stars on their musical knowledge and the results were less than impressive.

We'll forgive Emma Stone for not being able to get a few because those press tours have to be exhausting and mind-numbing so she's bound to be a little slow off the mark but there's no excuse for Ryan Gosling. He's just plain bad.
