Hidle Brown "H. B." Barnum is an American pianist, arranger, record producer, songwriter, and former child actor.
After winning a nationwide talent contest at the age of four and starring in the motion picture Valley of the Sun Marches On, Barnum continued his acting career on TV in the Amos 'n Andy Shows, the Jack Benny Show, and others, making his first solo recording as Pee Wee Barnum in 1950.
He then joined doo-wop groups the Dootones and, in late 1955, when Carl Gardner and bass Bobby Nunn left the Robins to form the Coasters for Atlantic, Barnum replaced Bobby Nunn as baritone and bass for the Robins, as well as playing piano for them. This version of the Robins recorded for the Whippet label, where Barnum soon became the A&R man. In 1960, under the pseudonym "Dudley" he recorded the radio hit "El Pizza", a parody of Marty Robbins' "El Paso". In 1961 he had the only hit under his own name, the instrumental "Lost Love", and in the same year recorded the first version of "Nut Rocker", credited to Jack B. Nimble and the Quicks. He also recorded three albums as a singer-pianist during the 1960s.
