In the Spirit is an appropriate name for Michael McDonald's first Christmas album because the ghosts of the Doobie Brothers are all over it. Which makes perfect sense since McDonald penned all but three of the songs in this collection. And while each make titular references to Yuletide, most of them would be at home either on a Doobies album or one of McDonald's solo discs, being that the subject matter is similar--overcoming obstacles, living in the moment, and the necessity of having deep convictions.
