Here are the words I can remember..

THey were called in from the hillside they were gathered from the glen
And the companies (I heard country) found them ready at the starting call for men
For no gallant son of freedom to a tyrant's yoke should bend
And a valliant heart must answer to the ______ call of friend

Keep the homefire burning while your hearts are yearning
Though the lads are far away they dream of home
There's a silver lining through each dark cloud shining
Turn the dark cloud inside out till the boys come home

Overseas their came a pleading help a nation in distress
And we gave our glorious laddies honor bade us do no less
