I recall reading about this on this site some time back but found another source on the web... quote

To offer headline acts in an area that was far from the Silver Circuit of casinos offering them, Jacobson gave Don Adams, Don Rickles, Woody Allen and Buddy Hackett a piece of the business.

He promised big time musical attractions – Sarah Vaughan, B.B. King, Frank Sinatra, Jr. (People went out of their way to hear Frank Jr.? Really?) On opening night in 1969 comedian Buddy Hackett appeared n*u*d*e on stage! (Correction: a former employee at Kings Castle says this happened in 1970)

You can read more detail on the blog of a stewardess who dated Jacobson briefly here:
