As a member of Los Panchos, he was the third voice and player of the requinto, a small guitar which he invented,[1] and is now a staple instrument.

[2] He was born in Teziutlan, Puebla, the son of a Lebanese immigrant Felipe Julián Bojalil and Carmen Gil.

After his brother Felipe "Charro" Gil's return to Mexico, Alfredo and Chucho Navarro remained in New York until they achieved fame in 1944, and with the Puerto Rican Hernando Avilés they founded the Trio Los Panchos, in which he remained in the period 1944-1981.

Third voice of the group, he is particularly remembered for his extreme mastery with the requinto, a small high register guitar, created by himself to reinforce the introductions and voiceless passages of the songs.

As a composer, many of his boleros are famous, such as Caminemos, Sin un amor, Hija de la mala vida, Basura, Tu ausencia, Solo, Cien mujeres, Me puniga Dios, No trates de mentir, Ni que sí, ni quizá ni que no, Un siglo de ausencia, Ya es muy tarde, Loco, Mi último fracaso, No te vayas sin mí and Lodo also known as Si tu me dices ven, among many others.
