The song features four saxes (three tenors and one baritone) in an arrangement that gives each “brother” a solo and culminates in a hard-swinging sax section chorus.
The song so typifies the sound of Woody Herman’s second “Herd” that the band is also known as the Four Brothers Band. The title also refers to the four musicians that played in the original version: Stan Getz, Zoot Sims, Herbie Steward, and Serge Chaloff. All four played in a light-vibrato style that was originated by Lester Young of the Count Basie Orchestra and popularized by Stan Getz.
In this rendition we have from the far left; Gary Anderson, then Frank Tiberi. The baritone player might be John Oslawski. Still lookin’ to figure out the third tenor player.
