Lambert, Hendricks & Ross - Cloudburst

Heard this song recently, in a different version, which reminded me how much I like Lambert, Hendricks & Ross. Joni Mitchell recorded two of the songs off the album from which this song comes. Annie Ross appeared in a movie directed by Robert Altman and Jon Hendricks appeared in a movie that starred Woody Harrelson. What does it all mean? As usual, I'm clueless. But it's a good song.
