Vancouver, BC:  I just spent a delightful couple of hours with a friend at the Waterfront Theatre on Granville Island watching the students of the  Arts Umbrella Musical Theatre Troupe perform The Drowsy Chaperone. Teens from 13 to 19 enrolled in the year-long Intensive and Pre-Professional  Musical Theatre programs get to showcase their work as in the current 2016 Expressions  Festival. This Festival also features work by the Theatre  Troupes of various ages.
