Mitzi Gaynor practicing for her early 1960's nightclub act
According to Life Magazine, August 4, 1961:
Miss Mitzi played the Flamingo Hotel. 1000 people were turned
away a night and the show was held over for 2 weeks.
She was leery about doing the show to begin with because as she said,
"I didn't want to compete with the booze and smoke" (page 49)
She was paid $40,000 a week and the hotel
agreed to help fund her next two films.
Mitzi ends her show by portraying movie queens from various eras
A 20's tango queen, a 30's European goddess a la
Dietrich or Garbo, 40's stripteaser, and finally her
turn as Nellie Forbush in the 50's era South Pacific
Here's a view of the Vegas Strip showing the Flamingo Hotel with
Mitzi's name on the bill. The sign appears near 7:49
