I have search all over the web with no luck so far on this one. Here is what I remember of this song: It was played back in the late '80s-early '90s. It was by a male artist, possibly Steve Green or someone close to him in sound. It is based off of Psalm 47:6. It was popular enough to make it on the radio at the time.
Lyrics are: "Sing praises to God, song praises Sing praises to our King, sing praises For God is the King over all of the earth Sing to Him a song of praise"
