Based on the Nat "King" Cole classic big band recording, this arrangement of "Orange Colored Sky" stacks a swingin' close harmony quartet on a walking vocal bass with soprano lead (either section or solo). Plenty of syncopated rhythms and playful background lyrics make this very fun to sing. The center "instrumental" section allows you to feature a quartet of your most impressive part singers. The a cappella arrangement of "Come Fly With Me" takes the listener on a trip around the world on the wings of one of Frank Sinatra's most iconic songs. Walking bass and playful background parts support a swingin' solo. Vocal percussion optional. "Caravan" - imagine Duke Ellington taking a year's sabbatical in Morroco: A wordless, rhythmically complex Middle-eastern tinged arrangement that breaks into straight jazz in the B section. S, A and T split in half with one trio echoing the other's tight horn sectin-like voicings. Vocal or standad percussion works well here especially multiple percussionists. With "Sing, Sing, Sing" you'll swear you hear an entire big band coming out of your voices in this lyricless take on Benny Goodman's classic recording. Not so easy to sing, but very impressive when all put together and a huge crowd pleaser. No solo, melodic lines move from part to part. vocal percussion is optional.
