What happens when two theatre nerds get together on a talk show? They perform a musical medley of course. 

Anna Kendrick stopped by The Late Late Show with James Corden last night and duo put on one hell of a show that included renditions of Shaggy's 'Wasn't Me'

Dionne Warwick's 'Say a Little Prayer'.

And Whitney Huston's 'I Will Always Love You'.

Here's the medley in full.
