Pygmy twylyte, solo section (A token of his extreme). Transcription: KS (update January 2014, deposited at the I-depot, The Hague).
Note: the curve in the bass line between brackets in bars 1-3 is roughly something what you can see Tom Fowler do on the DVD - and Zappa on his guitar - but I can't exactly hear what's going on. The sounding result of both, and the synthesizer, is approximated via the notated notes in staff 1. Probably they did the same during the Helsinki concert.
