One doesn’t need a tux and gown to dance to the Mood Swing Orchestra, but the music presented under the leadership of saxophonist Michael Young is in the elegant ballroom style of big band East Coast Swing and Lindy Hop. Mood Swing has performed regularly at venues from the Claremont Resort to Bimbo’s. The band was launched in 1995 and was chosen as one of the best local swing bands in the March 1999 issue of “San Francisco” magazine. Trumpeter Peter Anastos provides many of the arrangements of classic big band dance hits of the 1930s and ’40s by Count Basie, Duke Ellington, Xavier Cugat, Benny Goodman, Glenn Miller, and Artie Shaw. The tunes are ageless: “Take the ‘A’ Train,” “In the Mood,” “Harlem Nocturne,” “Come Fly with Me,” and dozens more!
