WHAT: The Wild Things Music Spring Rumpus WHERE: MCT Center for the Performing Arts WHEN: Fri., May 18, at 7:30 p.m. HOW MUCH: $20/$15 advance at amymartin.org. WHY: The Wild Things Music Spring Rumpus, which by name alone conjures the late Maurice Sendak?s wild imagination, is a fundraiser that supports singer-songwriter Amy Martin?s Wild Things Music Scholarship fund. The night will feature 5- to 50-something-year-olds singing their hearts out. You can expect a range: The Fledglings will perform a rendition of ?Michael Row the Boat Ashore,? The Wolf Pack covers The Decemberists? ?June Hymn? and Lady GaGa?s ?Born this Way,? and the F.R.O.G.S. get down with Adele?s ?Rolling in the Deep.? Proceeds from the Rumpus will help fund people who want to participate in the program but can?t afford the instruction fees.
