Erin is dancing through the Greek Isles in Mamma Mia! at the Merry Go Round Playhouse. 

Mamma Mia! has fast become the Finger Lakes Musical Theatre Festival's highest selling production of all time!
She is appearing in the ensemble, understudying Rosie and Tanya, and serving as the Vocal Captain.
(Subtlety is her strongest suit, as seen below.)
