This is the British group. For the original French group, see Les Swingle Singers.
When the original French a-cappella group disbanded in 1973, leader Ward Swingle went to England where he formed Swingle II with an expanded repertoire. Renamed The New Swingle Singers in 1978, The Swingles in 1986, The Swingle Singers around 1988 and The Swingles again around 2014. Ward Swingle continued actively with the group until 1985 and remained associated as musical advisor until his death in 2015. Two of the name changes coincided with his leaving the group, first as a singer and then as an advisor.
