My obvious choice:
MOLLY (1973)
Kaye Ballard sang "Go In The Best of Health" to the AUDIENCE.
In other words, show's over now, time to leave, please don't tell friends & family what you just endured the last 2 1/2 hours... :)
Show lasted a WHOPPING 68 performances on Broadway and Ballard didn't go near Broadway again for nearly ten years.
