Interesting comment about his Chinese bass regarding the removable neck; the first couple songs RTF did Stanley used his tenor Alembic, then a stage hand brought out his acoustic bass, Stanley started to check his tuning against JLP's violin and had to grab a wrench and (I assume) tighten the neck mounting bolt! Apparently, when he first played the bass the action must have been too high tipping him off to the loose neck.
Stanley only played the new Alembic on a couple of songs, most were on the tenor, with or without the octave pedal, usually with it engaged except for his solos when he "took off".
