'Hey!' juxtaposes a contemporary reggae-style song with a traditional carol, We three kings. The songs revolve around the partner keys of E minor and G major and the two-ina- bar (6/8) and three-in-a-bar (3/4) meters, which work in complement. The exuberant melody of Hey! is quirky and jerky but singers will pick it up quickly once they attune their ears to its style; We three kings is easier to learn, and is contrastingly legato, lilting and sober in mood.
