This is how I hear the song. The only line I am uncertain about is the one in square brackets. Bob Pegg slurs the line. It could be something else entirely to what I have given - the second part could be 'and paths are strewn with rubble'.

JOIN US IN OUR GAME
(Bob and Carole Pegg)

Instrumental intro

Come on good people join us while you may
Join us in our game
Come with us into our world and listen as we play
Join us in our game
Join us in our game

We sing of the North where dales echo with the dancing
Join us in our game
Where fiddlers play and ladies laugh as Mr Fox comes prancing
Join us in our game
Join us in our game

A goshawk may beguile you, a hanging man may haunt you
Join us our game
When singing streams turn icy, then the Green Man he may taunt you
Join us in our game
Join us in our game

But the seasons hide the sorrow on the faces of the people
Join us in our game
[As doubts conceal their dangerous flood and pastures strewn with rubble]
Join us in our game
Join us in our game

And there's singing in the churches and the fields as day is dawning
Join us in our game
Neddy played and Jacky sang and Clancy danced till morning
Join us in our game
Join us in our game

Instrumental break

Repeat first stanza
