Adiós muchachos is a 1927 tango composed by Argentinian pianist Julio César Sanders and Argentinian poet César Vedani. According to Francisco Garcia Jimenez, Sanders was inspired when after a night out with a group of friends in 1927 in the Buenos Aires district of Flores, one of them said goodbye with the words "Adiós, muchachos".
