Radio Luxemburg would play the tunes that BBC banned or refused to play. A real treat was to hear something from the Beach Boys instead of the British philharmonic and Petula Clark.
By the way, I prefer Petula Clark over the Beach Boys. My favorite songs of hers are Song of the Mermaid (1952), The Little Blue Man (1958) and Tout Au Long du Calendrier (through the whole calendar, aka Calendar Girl; 1961).
