Brad Paisley debuted a new “love song” on the Tonight Show With Jimmy Fallon last week.  Brad was talking about dodgeball, Blake Shelton, and suddenly he picked up his guitar.  Whiskeyriff.com says the unreleased  song is about that first romance.  When Brad asks Jimmy if he remembers his first romance, Fallon tries to keep a straight face.  At that point you know something good is coming.  It happens at the 1:46 mark.
