In 1959, tenor saxophonist Phil Urso recorded a terrific album for the Legacy label with The Jomar Dagron Quartet in Louisville, Colo. The Jomar Dagron Quartet wasn't a quartet led by a Jomar Dagron. In fact, there was no such person named Jomar Dagron. It was a first-name amalgam of drummer Jo Jo Williams, baritone saxophonist Marvin Halliday, organist Dag Walton and tenor saxophonist Ron Washington. All were from Colorado and played there. By the time of this recording session, however, Halliday had left to join Woody Herman, and Phil replaced him. Bassist Gene Klingman also was added. Interestingly, Billboard in June 1957, while reviewing the Jomar Dagron Quartet's Rocky Mountain Jazz album, noted the group needed a bassist. Phil had spent time in Colorado gigging with the quartet on tenor and baritone until 1964, when he returned to New York and rejoined Chet Baker for a few albums. Despite the personnel changes, the group remained the Jomar Dagron Quartet. .
