Here is the entertainment for this year’s 90th annual Saint Rocco's Feast! Back by popular demand — North Shore Acappella! Those troubadours of the “lost art of Acappella!!” Yes, those lovable and cuddly five gentlemen in that long running Malden institution will return on Saturday night Aug. 10 opening for Broadway headliners, The Midtown Men. N.S.A. have been around for what seems like an eternity — 35 years actually, but who’s counting!? The cast of characters has changed somewhat over time but this lineup featuring Tommy Duarte, Steve Gambale, Jimmy Martin, Vinny Straccia and Dennis Taylor are as talented and accomplished as any past crew.
