My Baby Just Cares for Me - Nina Simone

[Distant Cousin]

Hi guys,

I've charted this out into the key of the recording (A) from my Real Book, but I can't work out the slight change at the start of the instrumental section. Apart from that it sounds like they're the same chords... Can someone help me out? What chords does it change to?

Around 1:24 is the part I mean: http://www.youtube.com/watch?v=eYSbUOoq4Vg
