Yes, for me, too, that is the ultimate part, the reference song for any pianist, same with Sultans and drummers. In my opinion Jim didn't nail it until now. But we should not forget that it was him who created those famous parts on the album back in 2000, so it is more like "not back to form again", or maybe MK and his music have indeed involved so much since then that he cannot keep up. The same with his rather loud organ parts on Speedway: They are loud, but somehow too wild, not really fitting in the song in my opinion. I love however the organ parts on Haul Away, not sure if he or Guy does them.
