Rip Rense wrote an interesting account of the “salon evenings” that were held at Zappa’s house near the end of his life, and of how they came to be:
At Gail Zappa’s behest, the blenders roared every Friday evening about 6. In short order, Frank’s staff of invaluable studio wizards and office workers became duly sloshed, and took to verbally slaying the dragons-of-the-week in tones that can be gently described as rollicking. At first, the Boss merely tolerated this; grudgingly accepting it as a necessity for non-workaholics (…) This soon proved problematic. Running leviathan computerized keyboard systems required assistants — assistants who were not snockered — so in time, the labor fiend was forced to observe the Friday breaks.
He actually took a Margarita in hand.
