Robert Orrin Tucker (February 17, 1911 – April 9, 2011) was an American bandleader born in St. Louis, Missouri, whose theme song was Drifting and Dreaming. His biggest hit was Oh Johnny, Oh Johnny, Oh! (1939), sung by vocalist "Wee" Bonnie Baker.
Tucker and his orchestra remained active until the 1990s, when health problems forced him to retire. In 2003, Tucker was interviewed about his passion for music and his long career as a bandleader by the NAMM oral history program. He died on April 9, 2011, aged 100.
