On February 28, 1960; sweethearts-turned-good friends Bobby Darin and Connie Francis appeared on "The Ed Sullivan Show" and sang a nice duet of "You Make Me Feel So Young" and "You're The Top". According to Connie Francis's autobiography " Who's Sorry Now?", Bobby and Connie were elected "King and Queen of Hearts" in a nationwide poll of Disc Jockeys. Bobby and Connie were asking deejays and jukebox operators to "turn the tables on heart disease" for the 1960 Heart Fund campaign.

According to Connie's Biography on the A&E channel, this was the last time Connie ever saw Bobby. (They had been broken up by her father and Bobby married Sandra Dee by the end of the year.)
