From the wiki: “‘Theme from A Summer Place‘ was written by Max Steiner (music) and Mack Discant (lyrics) for the 1959 film A Summer Place. Originally known as the ‘Molly and Johnny Theme’ (for the two characters in the film portrayed by Sandra Dee and Troy Donahue), it was recorded for the film by Hugo Winterhalter. Percy Faith recorded the most popular version of the tune which spent an at-the-time record of nine consecutive weeks at #1 on the Billboard Hot 100 singles chart in early 1960. Faith’s recording still remains the longest-running #1 instrumental in the history of the chart.
