A beloved jazz standard, this nostalgic song encourages us to leave the bad times in the past and welcome the good times that lie ahead! Arranged for divisi mixed choir, the jazz harmonies ring out with an energetic swing statement of the melody, two short vocalese-inspired solos that give way to a tender and gorgeous ballad section, and a big build to a bold conclusion: "I'm packin' my bags and singin' bye bye!"
