"Dr. Mr. Fantasy" by Traffic is a quintessential track for any classic rock fan's collection. It is one of the decades signature tunes by one of the era's signature bands. One indication of a song's greatness is the number of cover versions performed and which artists performed them. "Dear Mr. Fantasy" was covered by the likes of the Grateful Dead, Jimi Hendrix and Crosby, Stills, Nash and Young. I would recommend this song to any fan of the Classic Rock genre.
