TV at the time was AM. The Light Programme, Home Service and Third Network were available in FM but only in mono. The Third Network (later renamed "Radio 3") went stereo in 1967. It was many more years before any popular music would be broadcast in stereo. I remember as late as the 1970's people buying enormous Hirschmann VHF aerials and aiming them at France in order to pick up something popular.
