Supposed Atmophere of Hit Factory During the Making of Double Fantasy

This is a paragraph from Chet Flippo's "The Private Years" which
appeared in Rolling Stone magazine in the 80s:
"They agreed to go into a studio and do an album and even a tour.  At
the Hit Factory in New York, Yoko forbade drugs and turned one room into
an
Egyptian Temple -- with palm trees, an antique white piano and white
phones for her.  Session musicians, who were used to coke and cognac,
were served sushi and tea instead.  Yoko put plates of sunflower seeds
and raisins before each musician's microphone.  Shiatsu masseuses were
on call for them."
I find this portrait comically stupid.  What business would Yoko have
telling people what they could and could not ingest?  She was a
chain-smoker and regular user of heroin and cocaine.  Fred Seaman
alleges she'd get drunk on Stolichnaya vodka (her lover Sam Green's
favorite) while running through her so-called songs.  Lennon smoked
marijuana, inhaled sufficient amounts of coke to seriously damage the
inside of his nose, and took shots from a bottle of whiskey that Jack
Douglas kept in a drawer.  Guitarist Earl Slick admitted that "I was
drinking like a fish -- and John, bless him, put up with it, I think
because I reminded him of himself."
The fact that Yoko would even *pretend* to have pushed sushi, tea, and
shiatsu massage on everyone is, once again, an indication of her
narcissism.
BTW, why would a white piano (an instrument I don't believe Yoko ever
learned to play) and phones be indications of an Egyptian temple?
