Melissa, I wish I knew...maybe by "googling enough" you can find it...it is indeed infamous, especially among those of us theater folk. Of course, this was at a time before any of us had VCRs and I remember my mother being absolutely stunned at Barbara Harris' Tony acceptance behavior. I remember that year Harris beat out Mary Martin who was in I DO, I DO. Mary Martin cohosted the Tony awards with Robert Preston. Preston was the star of I DO, I DO, along with Mary Martin, and Mr. Preston did indeed win the Tony award that night , but as I mentioned, his cohost did not, Mary Martin, obviously lost to Barbara Harris.
Still, what I remember most of that Tony telecast is Harris' seemingly "stoned" behavior and Robert Preston, towards the end of the telecast, briefly fumbling a line and Mary Martin taking his Tony award(that he had just won) away from him in jest, to punish him for messing up a line from the cue cards. :)
I began taping the Tonys in 1980, the year of DREAMGIRLS and NINE. So I have 25 years worth of Tonys. I wish I had them all from the very first telecast and on , of course.
