In 1962, Ward Swingle and a group of session singers were busy crooning background vocals for Charles Aznavour and Edith Piaf. Tired of the usual warm-up exercises, they decided to sight-read through J. S. Bach’s Well Tempered Clavier, and Mr. Swingle famously declared, “Bach’s music has a natural swing!” Over the years, performers have changed and the repertory expanded, but the magical swing has remained as fresh as ever — and that apparently includes the hips as well!
