From Zappa Wiki Jawaka
AGITTARIUS [16-18 / (-30º)-30º] one of the constellations in the "One Size Fits All" (1975) "universe", has a star called "Ernie"
Once upon a time (early '70s), he played (bass) in a group called Chunky, Novi & Ernie. "Novi" and "Chunky" are also stars of AGITTARIUS.
The star "Ernie" could easily be mistaken for Ernie Watts (the original Cletus Awreetus-Awrightus, Funky Emperor and way-hep Grand Wazoo megaphonist and tenor sax player).
