Heidelberg Quintet Lyrics Follow

The American Quartet was a four-member vocal group that recorded for various companies in the United States between 1899 and 1925. The membership varied over the years, but the most famous line-up — comprising John Bieling (first tenor), Billy Murray (second tenor), Steve Porter (baritone), and William F. Hooley (bass) — recorded for the Victor Talking Machine Company from 1909 to 1913. The same group of singers also recorded for Edison Records as the Premier Quartet (or Quartette), and for that and other labels as the Premier American Quartet. From 1912 to 1914 the quartet also recorded with countertenor Will Oakland as the Heidelberg Quintet.
