Variety: A pleasantly discursive guide to the longest-running music program in TV history, “A Song for You: The Austin City Limits Story” is the latest in a thriving subgenre of documentaries dedicated to the proposition that Austin is the live music capital of the world, if not the entire galaxy. Director Keith Maitland’s obvious labor of love could be classified as the cinematic equivalent of an authorized biography — after all, it’s co-produced by KLRU-TV, the public television station that produces “Austin City Limits,” and Terry Lickona, that show’s longtime producer, is one of this doc’s executive producers. But the movie generates too much good will to smack of crass self-promotion, which should extend its shelf life as home-video product, streaming fare and audience magnet during PBS fund-raising weeks.
