From Zappa Wiki Jawaka
I question whether we want to make links out of the two songs listed here that feature Ms. Coffee. These were two unique performances relative to nothing other than that particular show.
Or do we intend to have a show by show analysis here also? If so, then it makes sense to me.
(Boy, good luck to whomever takes THAT one on...)
Regarding the following statement:
"... guest vocalist with Zappa's band in New Jersey on 11/07/1973 (early show)" Based on JN's list, on 7-Nov 1973 FZ played at the Orpheum Theatre in Boston, MA (one gig only), while he was at the William Patterson College in Wayne, NJ (2 shows) on 11-Nov 1973.
All the best
