A little Saturday-morning treat for you:
Dick Shawn does his marvelous star turn as Lorenzo St. DuBois in "The Producers" (1968). I refuse to see the Broadway version because Mel Brooks cut this song out (he didn't write it).
I used to perform the song at an open mic in Greenwich Village, wearing a homemade Campbell's soup-can necklace just like Shawn's. I would wear a minidress with tights and fishnets over the tights, and I would have silk flowers poking out of the fishnets at odd angles. At the appropriate moment of the song, I would toss the flowers out to the audience. It was very hard to do that and play guitar at the same time.
(There's more on my dissipated years, and my recovery from them, in my upcoming book — which some wit at Amazon has appropriately coupled, in a "buy two/get discount" offer, with Compendium of the Catechism of the Catholic Church.)
