While many fans perceive this song as being inspired by the Steven Spielberg film E.T., it is really about a school in Southern California that’s actually called “Heartlight”. The song was inspired by writings from students from that school. On most pressings of High Adventure and on some Loggins greatest hits compilation albums, it is officially titled simply “Heartlight”. The title was expanded to “Welcome to Heartlight” to avoid confusion with Neil Diamond’s song also called “Heartlight”.
It was released as a single in early 1983 and peaked at number 24 on the U.S. Billboard Hot 100 and number 17 on the Adult Contemporary chart.
