 These returned migrants, popularly called "indianos", also brought back their songs and their music, which were soon included in the repertoire of flamenco artists, after a process of adaptation to the flamenco style of singing and playing.Although Antonio Chacón already sang these styles (he recorded the milonga in 1913), the first flamenco singer who recorded a significant repertoire of guajiras, milongas, and vidalitas was Manuel Escacena.He made popular the milonga "Juan Simón", which he learnt from Mexican bullfighters around 1911, and which was later recorded by several other singers.
