Under the Boardwalk” is a hit song written by Kenny Young and Arthur Resnick and recorded by The Drifters in 1964.
The lyric describes a tryst between a man and his beloved in a seaside town, who plan to privately meet “out of the sun” and out of sight from everyone else under a boardwalk.
The instrumentation includes güiro, triangle and violins. The song’s chorus is unusual in that it switches from a major to minor key.
The opening line of the song references the Drifters’ prior hit “Up on the Roof”, showing the occasional thermal weakness of the rooftop getaway and setting the stage for an alternate meeting location, under the boardwalk. (source Wikipedia)
