"You're Driving Me Crazy (What Did I Do?)"

The for for this song at the highest level is two sixteen-bar sections.  The first sixteen bars form two eight-bar phrases.  The second phrase is basically a repeat of the first, so it is designated as AA.  The second section is also two eight-bar phrases.  The first is new material (the chorus), which is followed by a repeat of the initial phrase.  The complete form is then labeled as AABA.  This entire form is often referred to as a chorus for soloing purposes.
