I had the song's last line first, and it seemed to me that anybody singing that kind of lyric would have to be some kind of a bad boy, who was really clueless. It's all BIAB RealTracks, nothing else -- the style is TMEXCT3, except that I replaced that style's accordian track with the harmonica track from POPHFST, and it seemed to work. The tracks were put together in Logic Pro X, using Logic's FlexPitch for the harmonies. All comments welcome.
