Gordie Sampson had already established himself as a passionate singer/songwriter in his native Canada before moving to Nashville in 2005 to write for others. His craft is obvious in the tear-tugging Carrie Underwood ballad “Jesus, Take the Wheel” and his cowrite with Texas legend Guy Clark on the bittersweet “My Favorite Picture of You.” And Sampson’s rollicking side shows on another huge country hit, Luke Bryan’s frisky “Knockin’ Boots.”
