Yolanda Be Cool is an Australian House/Electro band made up of Sylvester Martinez and Johnson "Durango Slim" Peterson. The name is a reference to the film Pulp Fiction, where the character Jules (played by Samuel L. Jackson) shouts "Yolanda, be cool" to a female armed robber named Yolanda (played by Amanda Plummer).
They collaborated with Australian producer DCUP (real name Duncan MacLennan) to release an international single "We No Speak Americano" on the indie Australian label Sweat It Out they founded, sampling on a 1956 [neapolitan dialect] hit "Tu vuò fà l'americano" by Renato Carosone and written by Carosone and Nicola "Nisa" Salerno.
