'Victor Sylvester's Ballroom Orchestra' was one of the leading dance band of the 1940s era. Victor Sylvester's early career was as a world champion exhibition dancer, who was also teaching ballroom dancing with his sister Gwen. In the late 1920s and early 1930s, there was a lack of good dance recordings that featured a constant tempo, something Sylvester needed for his dance studio. Most of the studios used a rather simple hand-wound phonograph to play recordings. With characteristic verve, Sylvester assembled a few musicians and made his own recording featuring songs with the pronounced beat so needed by dancers. Soon, other dance instructors were buying his records. Among his releases were "Ballroom Dancing with Victor Silvester & His Ballroom Orchestra", and "Dancing On My Heart". Interestingly, he also authored the book "Victor Sylvester's Modern Ballroom Dancing." Victor Sylvester held the record for the longest running weekly BBC radio program with his show that ran continuously for 25 years. The band was heard on the "Beeb" all through the World War 2 years. Then, -continued as the first ever television dance program on TV. -- Source of annotation: Marvin or Ruth Sackner.
