Caravana Musical (then 'Vuelo 605') was a Spanish radio program presented by Ángel Álvarez in the 1960s-1980s. This publication is related to that radio program. Ángel Álvarez was the first one to play Bob Dylan, Joan Baez, The Byrds and the American folk singers on the Spanish radio. He was very popular and the emotion was great when he died in 2004.
