Also, not to go too far off topic, but can
somebody please identify the source of this studio performance of "Hejira?" Was it ever released as a recording or a video? It is absolutely
smoking 
. I'm not usually into this kind of
masturbatory jazz improv/fusion stuff, but this has such a strong groove. I am guessing it was done sometime between
Night Ride Home and
Turbulent Indigo.
