Whats Worth Watching: ‘So You Think You Can Dance’,’Whose Line is It Anyway?’ and more for Monday, July 13

So You Think You Can Dance, “Top 20 Perform” (Monday, July 13, 8/7c, Fox)

If there’s any performance show where you may need to exercise caution in wishing anyone to “break a leg,” it’s So You Think You Can Dance, the grueling yet exhilarating competition series that has had its share of injuries over its dozen seasons. Even as this year’s crew of Top 20 dancers was announced last Monday, the jubilation was tempered by news that one of the finalists had suffered a physical setback and would not be able to participate. Who that is, and who will replace her or him, will be revealed in tonight’s first live show. We’ll also finally get a sense of how the new format works, which separates the contestants into groups of 10: “Team Dance” (trained dancers mentored by Travis Wall) and “Team Street” (raw talents from the more free-styling world of hip-hop and its derivations, coached by Stephen “tWitch” Boss).

Beyond the always-spectacular hoofing we’ve come to expect on Dance, highlights of the live broadcast will include a performance by judge Jason Derulo of his new singles “Cheyenne” and “Get Ugly,” and an interview of super fan Michelle Obama by host Cat Deeley. Next week, one dancer from each team will be eliminated, and it won’t take long before we start rooting for our favorites from each school of dance.
