Auditions for the “So You Think You Can Dance?” show were held at the Cadillac Palace Theater in Chicago on Thursday. Hundreds of hopefuls lined up outside and down the block, since early in the morning. Around 7am, cameramen with the show started stirring up the crowd and filming people in line showing their dancework . At left was an associate producer, who brought a group of women into the street to flaunt their moves. A lot of energy, excitement, enthusiasm – and young people – were in the air. A fun morning… There’s an online gallery of some other images, including the show’s host.
