After starring in the West End productions of Ghost and Wicked and the national tour of The Book of Mormon, Welsh star Mark Evans makes his New York stage debut as the comical and feisty leprechaun Og in Irish Rep's acclaimed off-Broadway revival of Finian's Rainbow

Evans in 'Wicked', 'Ghost', 'The Book of Mormon' and 'Finian's Rainbow'

On December 3, Mark Evans took over the BroadwayBox Instagram to bring followers behind the scenes of a two-show-Saturday at Finian's Rainbow. Scroll on to see the excitement, the songs, and the killer captions.

'An actor prepares' The legendary Ken Jennings freshening up before becoming Finian! And believe me, he well and truly BECOMES Finian! This is a man that everyone should experience sharing a dressing room with. He holds a special place in my heart! He's a dream! @irish_rep @markevansonline #finiansrainbowtakeover

Places call means I get to put my feat up! This lephrechaun makes a fashionably (?!) late arrival 20 minutes into the show! My Michael Flatley standard dancing has scuffed these bad boys real good! #notanirishdancer #finiansrainbowtakeover #finiansrainbow #og #leprechaun @irish_rep @markevansonline
