So You Think You Can Dance - Season 4 Episode 2

It was freezing cold outside in Salt Lake City, site of the first set of auditions in Tuesday's two-hour episode of "So You Think You Can Dance?" Would the dancers heat things up inside? Guest judge Mandy Moore joined judges Nigel Lythgoe and Mary Murphy for two days in Utah as they came away with 42 dancers who moved on to the Las Vegas audition. As usual, the dancers each had one minute to dance for the judges, after which they'd either get a ticket to Las Vegas for the next round, be sent home, or be asked to join the group choreography routine at the end of the day for a second chance.
