( backing track 4-11/6/1984, organ added 2003 ~ 2:25 )
Never having been on drinking terms with the STAX brass section, I achieved a fair imitation by feeding the Roland SH-101 synth via the MuTron III and letting it overload.   The organ is MIDI-generated.

Originally a backing track for the lyrics of an unhinged acquaintance, this now provides a spangly backdrop for my incarnation as 1960's nightclub Hammond-maestro.

This picture shows a modern copy, made by HAZ.

Its circuitry is completely different from the original, but the controls are basicly the same.
