Yolande and the Professors

From the "Just Plain Ray" comedy skit on the television series The Ray Stevens Show (1970).

A Carmen Miranda-type singer (presumably Yolande) with a giant fruit hat fronts a string quartet. After singing for 12 seconds, she's knocked unconscious by one of the cello players, and the quartet devolves into a slapstick fight.

Later in the same skit, a lumberjack mentions Los Amigos de las Cucarachas.
