Each year, the Children’s Music Showcase at Homegrown features a different array of performers and one simian sensation. Dan the Monkey Man is the mainstay, having played the showcase each year since 2016. The man under the monkey ears is Dan Munthe, who plays for grownups in two other bands at Homegrown — Deep Fake Five and Life Parade. But when he pins on the curled tail for the kiddos, it’s a rambunctious dance and art show where any primate can sing along.
