The Active Age and Crown Uptown Theatre are giving away four pairs of tickets to see Gunhild Carling, a Swedish performer who sings, dances, juggles and plays 11 musical instruments — including three trumpets at once on one song. Backed by a big band, Carling specializes in the classic jazz of 1920s era New Orleans, but also is known for swing. Win tickets to Sweden’s ‘Queen of Swing’ versions of songs such as Abba’s “Dancing Queen.” Audience members are encouraged to dance.
