The Jacksons are scheduled to perform at an outdoor concert, but when Michael discovers a talking "blues bird" (a play on "blues" and bluebird) and learns that the jazz-musician voiced bird and his nest, containing an egg soon to hatch, are in danger from bulldozers scheduled to tear down the concert park, Michael investigates. He learns a wealthy magnate named Hoozis owns the building overlooking the endangered park, and at once moves in to interfere. Hoozis is patterned after eccentric U.S. millionaire Howard Hughes.
