In the years either side of 1975, a revolution took place in English Social Dance. The dominant force throughout the 20th century had been the English Folk Dance and Song Society. There had been a previous major change in the first years after 1945 when the young royal princesses took an interest in square dancing after visiting Canada. The EFDSS heartily endorsed this and the bands that played for their ubiquitous dance clubs adopted many of their reels and played them at speed.
