In the age of electronic entertainment, how delightful to see a roomful of children wrapped in the spell — not of a movie, video game or Web site — but an old-fashioned puppet show. Che’s Lounge in Vineyard Haven played host Sunday, Feb. 15 (the second of three consecutive Sundays scheduled) to a local puppet troupe performing a Brazilian folktale — Toad and the Party in the Sky — to a packed house. Children in the audience, ranging in age from one to ten, were clearly captivated, laughing aloud and even singing along with the characters.
