Doctor Who show, as the story begins anew with each companion and she undergoes more change than the Doctor. The primary companions of the Ninth and Tenth Doctors were Rose Tyler (Billie Piper), Martha Jones (Freema Agyeman), and Donna Noble (Catherine Tate) with Mickey Smith (Noel Clarke) and Jack Harkness (John Barrowman) recurring as secondary companion figures. The Eleventh Doctor became the first to travel with a married couple, Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill), whilst out-of-sync meetings with River Song (Alex Kingston) and Clara Oswald (Jenna Coleman) provided ongoing story arcs. The tenth series introduced Pearl Mackie as
Doctor Who radio station Classic FM's Hall of Fame, a survey of classical music tastes. A revised version of Gold's 2010 arrangement had its debut over the opening titles of the 2012 Christmas special "The Snowmen", and a further revision of the arrangement was made for the 50th Anniversary special "The Day of the Doctor" in November 2013. Versions of the "Doctor Who Theme" have also been released as pop music over the years. In the early 1970s, Jon Pertwee, who had played the Third Doctor, recorded a version of the Doctor Who theme with spoken lyrics, titled, "Who Is the Doctor".
