"Shangri-La" is a popular song written by Carl Sigman (lyricist), bandleader Matty Malneck, and Robert Maxwell in 1946. The term comes from "Shangri-La," the hidden valley of delight in James Hilton's 1933 novel "Lost Horizon." The term "Shangri-La," especially in the 1930s and 1940s, was slang for heaven or paradise, and the song is about the joy of being in love.
Composer Maxwell's instrumental version (saxophone/organ lead with brass and rhythm) charted in 1964. Other popular versions (with lyrics) were recorded by The Four Coins in 1957 (#11 US) and by The Lettermen in 1969 (#64 US).
