A rough outline is
1 It was such a lovely day, the sun was shining bright ....
I know the peace speaker, I know him by name,
I know the peace speaker, he controls the wind and rain,
when he says peace be still, they have to obey,
I’m glad I know the peace speaker, yes I know him by name.
2: There’s never been another man with the power of this friend ...
Coda: Peace, peace, wonderful peace ...
