The song, which is sung by the main villain, wins you from the first chords. To be specific – chords and seductive whisper with an accent, after which the most luxurious rock rattles, which only can be afforded by children's cartoon. Voice of Alan Cumming sounds with an expressive, right husky, which is mixed with sinister laughing. From the middle, the song transforms again into a musical and melody becomes better, funnier, and it is much harder to believe that the hero is a notorious villain.
