Don Francisco and Jimmy Fallon perform on The Tonight Show Starring Jimmy Fallon on Nov. 1, 2016.

Don Francisco and Jimmy Fallon, two television titans, came together during last night's episode of The Tonight Show Starring Jimmy Fallon to give one epic rendition of the classic "To All the Girls I've Loved Before," initially made famous by Willie Nelson and Julio Iglesias in 1984. 

The idea for the late night presenter and Don Francisco to share the stage came from a fan who sent in the request via mail. 

"I love Don Francisco, he's a legend. But unfortunately there is no way to get him here right now," Fallon responds to the viewer. "Well, there is one way. Legend has it that he can be summoned by the power of song. I can give it a try." 

Fallon begins to sing "To All The Girls I've Loved Before," and before he knows it, the legend himself walks onstage to sing the duet. Watch the epic moment below: 

Don Francisco recently premiered his Telemundo talk show Don Francisco Te Invita, just a little over a year after closing a chapter with Univision, ending his variety show Sábado Gigante after 53 years on the air -- the longest-running variety show on television.
