Today is the day for Blue's big backyard music show. But when Tickety loses her voice, we need to play Blue's Clues to find Blue a new singing partner, even as we prepare for the Big Music Show! It's the first "Blue's Clues" full-length movie, introducing six new songs and a cat named Periwinkle! "Blue's Big Musical Movie" is a blast with Ray Charles as the voice of G-Clef!
