The specials were executive produced by Richard Cox, who established Doyle Dane and Bernbach’s TV division in the mid-1960s. According to Monsanto’s corporate magazine, Monsanto Nights were seen by more than 32 million viewers. Streisand did at least three specials for Monsanto, including the one above, a filmed concert in Central Park. To see some real pros in action, watch Pearl Bailey and Carol Channing live at the Winter Garden Theatre, which I believe was one of the programs aired in 1969 (sadly no Actionwear stockings commercials are included).
In more recent years, Monsanto became a loathed corporate name plagued with scandals related to the safety of their pesticides (this was in addition to their role in producing Agent Orange in the 1960s); the company was acquired by Bayer in 2018.
