Anita O’day, one of my favorite scat singers, had a great sense of humor, swing, and improvisation. Her rendition of “Tea for Two,” which captured in Jazz on a Summer’s Day, at Newport Jazz Festival 1958 demonstrates her melodic invention. Even though the tempo is expeditious, she never sounds overwhelmed. Love the way she masquerades her voice around the melody and interacts with the band. That’s how you work with a standard, baby!
