Gulliver Dark is a lounge singer in Springfield.
Dark is seen singing at the Sapphire Lounge near the Ye Olde Off-Ramp Inn. He sings "If I Could Love A Million Girls" right before Homer makes his speech about not seeing women as objects. After hearing Homer's plea, he is moved by it and calls his own mother in tears. Dark is also the singer in Tito Puente's band.
Dark also appeared, played by McMurray, on The Tracey Ullman Show in several skits during the time the original shorts were included on the show.
