Russell Davies celebrates the art, craft and inspiration of the popular song. "Hotels" and "The One I Love" are the two main themes today, beginning with a song Michael Feinstein recorded in the Algonquin Hotel. Fred Astaire performs Puttin' On The Ritz and Russell delves into the origins and subsequent meanings of "Ritz". Songs driven by the idea of "The One I Love" give us Cooking Breakfast For The One I Love and The One I Love Belongs To Somebody Else, amongst others, and are concluded with Uke Maestro Lyle Ritz and Rebecca Kilgore doing Jobim's Once I Loved.
