Los Hooligans (Mexico) launched this rare blue vinyl in1961 under Phillips Records. Originally composed by Eddie Medina (Freddy Fender). Singing: Ricardo Costa. "No está aquí" is a pre-Twist song. Twist music (and dance) was rapidly separated from rock and roll in 1961, getting its own entity in 1962. There are more songs like this, and I shall upload some of them. For more pre-twist songs, I highly recommend the blog Del Rock al Twist! Enjoy!
