Sammy Day and His Swing and Sway Orchestra
Swing group of tiny Pixies from the Pete Pixie/Mighty Atom story of comic book The Pixies #2 (Spring 1947). They're so small, they use an old boot for a bandstand.
They play a benefit party for poor pixies at Pixerary Park.
The name is a parody of Sammy Kaye and His Swing and Sway Orchestra.
