Katy Perry's hit from Summer 2012 (featured in her movie "Part of Me") is set for vocal jazz ensemble in either mixed or treble choir setting (both versions featured below). Just a touch of reharmonization to add an element of surprise, but otherwise, driving and strong, like the original.
notated piano, bass and drums. Synthesizer for keyboard, bass and even drums works well, as does performing with the Rhythm Track.
