Ive just listened to this band and I really liked it. They were from Argentina and the leader was Charly Garcia (an argentinian musician, considered a musical genius). The band is La Máquina De Hacer Pájaros (Something like "The bird-making machine) and the song is "Ah, te vi entre las luces" (I saw you between the lights) [ame=http://www.youtube.com/watch?v=9se2ZYOJCis]La Maquina De Hacer Pajaros - Ah, Te Vi Entre Las Luces (1976) - YouTube[/ame]
