For the American singer also known as Marco Antonio Muñiz, see Marc Anthony. Marco Antonio Muñiz (born March 3, 1933) is a singer from Jalisco, Mexico.[1] Known all over Latin America, Muñiz has declared publicly and in most countries he has visited, that Puerto Rico is his second country, and many Puerto Ricans consider him to be an "honorary Puerto Rican". A few Puerto Rican song standards (such as the danza "Alondras en el bosque") have Muñiz as their definitive interpreter. He also acted in Sinful.
