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.

Another line-up credited with the same name comprised Albert C. Campbell, W. T. Leahy, Dudley, and Hooley, on recordings for Victor from 1901.

[1] The best known line-up of the quartet was formed in 1909, when Victor Records needed a vehicle for their new singing star, Billy Murray.

[3] Bieling left the group in mid-1913 because of the strain on his voice, which worsened when he was required to make "cowboy whoops" on some records.

The group continued thereafter, with Hooley replaced by bass singer Donald Chalmers who, like Young, had been a member of the Criterion Quartet.

This was agreed; the group signed exclusively to Victor, with Murray and Burr receiving $35,000 each per year, and Campbell, Meyer, and Croxton $10,000 each.
