As their older brother Clydie began breaking away from classical music to study jazz, he introduced his sisters to the new syncopated style and to many of the young jazz players in New Orleans. Leon Roppolo (clarinet, guitar), Monk Hazel (drums, cornet), Pinky Vidacovich (clarinet, saxophone), Nappy Lamare (guitar, banjo), Ray Bauduc (tuba, vocals), Dan LeBlanc (tuba), Leon Prima (trumpet), Louis Prima (trumpet, vocals), Wingy Manone (trumpet, vocals), Al Gallodoro (clarinet, saxophone), Chink Martin (bass, tuba, guitar), Santo Pecora (trombone), Raymond Burke (clarinet, saxophone), and Tony Parenti (clarinet, saxophone) were regular guests at the Boswell home. The sisters were particularly influenced by the cornetist Emmett Louis Hardy, another friend of Clydie's, whose well-documented talent and skill helped shape the sisters' knowledge of jazz harmony, syncopation, and improvisation. Hardy and Clydie both died young and unrecorded, Hardy of tuberculosis at age 22 and Clydie of flu-related complications at 18.
