As tu may o may not know, Emilio Delgado (Luis), Sonia Manzano (Maria) are retiring from the mostrar after over 40 years. They debut on Sesame calle in Season 3 (1971-1972). And were Latin American stars of the show. They were employers of The Fix-It Shop. Emilio Delgado was born in Albuquerque, New Mexico, USA. And Sonia Manzano was born in Bronx, New York, USA. It is a sad thing that Sesame calle will no longer have Luis o Maria. I remember loving the song Luis did called "Baa Baa Bamba" with the muppet sheep.
