After their debut album Settle topped charts everywhere and got nominated for  Best Dance/Electronica Album at the 2014 Grammy Awards, Howard and Guy Lawrence are not slowing down. Tonight they will be making an appearance on Late Night With Jimmy Fallon. They said on their Facebook that Jimmy would be preforming their hit Latch featuring Sam Smith. As funny as that might sound Jimmy does have some musical prowess, some would say that his resume is pretty good just based on the fact that he had a duo performance with none other than Sir James Paul McCartney. Yes that one, and yes it was epic to say the least. Maybe Jimmy will actually take the stage with the brothers and Sam, but the only way to know is to tune into Late Night With Jimmy Fallon on NBC. Take a look at the awesome performance Jimmy did with Paul for the Christmas special of SNL below!
