Perhaps this “singing scoopers” thing needs to be reevaluated: I headed to a local Ben & Jerry’s to get a cone, only faintly realizing something was amiss. Once inside, I shared the space with a very confused tourist family, a few panhandlers asking for ice cream, and… two dozen voices packed behind the counter — the cast of “The Lion King,” playing down the street — who broke into “The Circle of Life” at top volume, including clapping, and at very close range. One singer managed, somehow, to take my order, and I escaped largely unharmed.
