A comedy show by Tina Friml will benefit Spark, a nonprofit that uses assistive technology to help people with disabilities to live, work and play more fully and independently. The organization was formerly known as East Tennessee Technology Access Center. Limited seating is available, and attendees must be 18 or older, unless accompanied by a parent or legal guardian. Friml, who is from Vermont, engages audiences with her off-beat, animated take on disability and the social assumptions about it. Doors open at 7 p.m.
