Brad Pais­ley joined Col­bie Cail­lat for her new hol­i­day project, “Christ­mas in the Sand.” “I had recorded ‘Merry Christ­mas, Baby’ with more of a coun­try style to it because we did Bruce Springsteen’s ver­sion, which had more of a blues, rock, coun­try vibe,” she said. Then her man­ager sur­prised her. “He said, ‘You know, Brad Pais­ley is under our man­age­ment. Maybe we could ask if he wants to sing and play gui­tar on the song,’” she recalls. Col­bie is set to per­form the hol­i­day song on ABC’s upcom­ing “CMA Coun­try Christmas”
