"California Nights" is a song written by Marvin Hamlisch and Howard Liebling and recorded by Lesley Gore.
The chorus includes multiples long tones over abnormal chords and the verses are noticeably accompanied by a soft electric piano.
Billboard described the song as a "production rhythm ballad with groovy dance beat and strong vocal work has the hit ingredients to put Miss Gore back up the Hot 100.
"[3] The single peaked at number 16 on the Billboard Hot 100 in March 1967 but stayed on the chart for a then-lengthy 14 weeks,[4] ranking 61 in the year-end Top 100.
An edit of the song (removing the second verse and refrain) was lip-synced by Gore on the January 19, 1967 episode of the TV series Batman, "That Darn Catwoman".
