Television legend Don Francisco made a surprise, musical guest appearance on "The Tonight Show Straring Jimmy Fallon" to sing a duet with Fallon.
Fallon starts the segment taking requests from one of his viewers named Mike Ronaldo, who requests Francisco join The Tonight Show to talk about his new Telemundo series "Don Francisco Te Invita."
"I love Don Francisco. He is a legend. I would love to have him on," Fallon begins, "but unfortunately there is no way I can get him here right now."
"Well, there is one way," Fallon continues. "Legend has it that he can summon him through the power of song."
Fallon begins singing Willie Nelson's intro for "To All The Girls I've Loved Before," and then Don Francisco takes the stage to sing Julio Iglesias' part.
Don Francisco, the Chilean TV host known by millions for his 50-plus year career with "Sábado Gigante," signed a multi-year deal with Telemundo in March to produce content for Latino and international Hispanic audiences.
Don Francisco, whose legal name is Mario Kreutzberger, also appears on Telemundo as a special news correspondent to conduct high-profile interviews.
