In old Mexico I stand on the square in Matamoros Round the plaza the couples are walking to music so sweet I found my love not too long ago in Matamoros But I'm feeling low as the beggar who sits in the street Oh the promises that she made with eyes black as midnight How could I know how fickle her promise could be Now I'm back to find what I feel is mine in Matamoros And there'll be bad trouble if I catch her cheating on me Streets are narrow and dark and Tequila runs free in Matamoros I stop for one moment outside of Miguel's swinging door My heart breaks to hear the same haunting sound of Grenada She once called it our song and vowed she'd be mine evermore Then across the square with this wild young Vaquero I see her Laughing and dancing and tossing her raven black hair Fate may take a hand when I face this man from Matamoros For the love of my woman is one thing that I'll never share Now I walk in the night far away from the lights of Matamoros And recall the last moments when I knew she loved me more than life I can still hear her cry I love you and I'll prove it Mañana Then seeing my danger she jumped in front of his knife I know the stories they'll tell in the dim lit casinos Of the raven haired beauty who for her love lay dead on the floor They'll speak of the fight with the gringo that night in Matoamoros And wonder what happened for he never returned anymore
