Saturday-Sunday. Augustana Arts explores the playful days of childhood in “Fairly Tales, Games and Make-Believe,” the organization’s annual family concert.

Augustana Lutheran Church, 5000 E. Alameda Ave. 3 p.m. Sunday. Abiding Hope Lutheran Church, 6337 S. Robb Way, Littleton. Tickets are $10 for adults, seniors and students; $8 for kids ages 5 to 12.
