Fifty-fifty, organ solo section. Transcription: KS (update 2013, deposited at the I-depot, The Hague).
Note: the Cb Mixolydian part would normally be notated as B Mixolydian with four sharps. Cb Mixolydian reads difficult, especially since it involves a B double-flat, but changing from a larger number of flats to a larger number of sharps doesn't look nice neither. So I went along Paul Pappa's choice for Cb in the guitar book (as a guitar book this book offers the guitar accompanying chords only for solos not by Zappa).
