My husband was a musician since his schooldays. He played byrequestat
various private celebrations etc and throughout the war(2nd) was asked
to play for US army personnel at a camp nearby and also village halls etc. all of which were sited in the country. Music was licenced in the town pubs, if I remember correctly, around the 50s era but never in my experience out on the frontage-either singing or playing an instrument. In fact the sound of all music and singing was kept entirely inside the relative pub.
