For the flip side of the single, Tom Wilson added a song that Simon and Garfunkel had recorded a few months earlier when they were trying for a more "contemporary" sound.  "We've Got a Groovey Thing Goin'" wasn't anything like the serious-natured hit song on the "A" side; when the Sounds of Silence album was rushed to the stores after the success of the newly electrified single, the liner notes about this song said simply:  "Just for fun".  Paul Simon seemed to like the now somewhat embarrassing Sixties slang term "groovy"; he also wrote "The 59th Street Bridge Song (Feelin' Groovy)".
