Fitz and the Tantrums' undeniably catchy hit The Walker (released December 10, 2013) was featured prominently in a promo campaign for the 2014 Oscars, as well as in a spot for Laughing Cow cheese, USA's Suits, and CW's The Vampire Diaries. While the group readily acknowledges their retro influences, The Walker also bears a strong resemblance to Velvet Hammer's 1977 funk/soul classic Happy. Similarities include: key (D/Dminor, both songs used "borrowed chords" or "mode mixture"), chord progression (TW: D-G-F-G or I-IV-bIII-IV; Happy: D-F-G-Bb or I-bIII-IV-bVI), and melody (the whistled melody in the Walker and the string part in Happy both revolve around a D minor pentatonic scale that emphasizes eighth notes). Check it out: The Walker (:23) VS Happy (:28).
The Walker also shares some characteristics with Edwin Starr's Twenty-Five Miles (released 1969), XTC's Generals and Majors (August 1980), and Stone Temple Pilot's Big Bang Baby (released March 23, 1996).
