However, a plena standard to this day was born when seamstresses of a local handkerchief factory struck against the factory's owner, Lebanese industrialist William Mamary, and Mamery hired replacement workers (whom the seamstresses considered to be scabs). Don Mon wrote ""Aló, ¿Quién Ñama"" (loosely translated as ""Hello, Who' Calling?"", sometimes referred to as ""Qué Será"") as a musical description of the strike. Since the seamstress' strike was organized by local labor leader John Vidal, and patronized by local assemblywoman María Luisa Arcelay, they are mentioned in the song. The seamstresses are reportedly calling each other as to raise mutual concern about the poor pay they're getting. Near the end, Don Mon breaks into what his son later called ""trabalenguas"" (tongue twisters), which in fact is a style of scat singing where some of the syllables of the actual song are slurred nasally and delivered quickly along with the scatting. The skill was passed from father to son; Efraín became so adept at using "trabalenguas" that he eventually was called ""El Rey del Trabalengua"" (""The Tongue Twister King"") once he became famous.
