Wow, I didn't realize that Isaiah 2:3 and 2:5 are choruses I know.  The chorus for 2:5 that comes to my mind is "Let us all get together in communion suite and walk, walk in the light.  Let's love one another 'till the Saviour we meet and walk, walk in the light. Walk, in the light, walk, in the light, walk in the light; let's walk in the light of the Lord"
