 However the success of the band led to Mondéjar and Jorrín over whether the bandleader or songwriter should take the credit for the invention of the cha-cha-chá.The band split during a tour of Mexico in December 1954 and Ramos returned to Havana with half of the band to form Orquesta América del '55 in 1955.During that same year Juanito Ramos was replaced by Rolando Lozano flutist (formerly of Orquesta Aragon) and his brother Clemente Lozano also a flutist.
