Here's "Wey, hey, Rock and Roll" thanks to Google. I've changed a word here and there, to conform with the lyrics as I remember them. Also, the last verse below was not on the version I found through my Google search.

I liked to sing this with a different chorus that went like this:

Halo, halo infantry
Queen of Battle, follow me
Canadian life's the life for me
But nothing in the world is free

That's how I heard it in 2004, but I'm sure that "Canadian life" was something else in the original. The tune was also different from the tune that is commonly sung to to "Way, hey, Rock and Roll".

Rock n' Roll - Call & Response

Chorus: Wahey Rock and Roll
Wahey Rock and Roll
A little bit of rhythm and soul
Early in the morning

You've landed on the beach again
Your orders are, you're diggin' in
The rising sun's a beautiful thing
Early in the morning

Chorus
You stand-to when the sun goes down
You're watching all the ground around
You stand to watch it rise again
Early in the morning

Chorus

From the bush a rustling sound
Someone's moving on your ground
The enemy's lying all around
Early in the morning

Chorus

The enemy starts a creeping in
Machine gun crews begin to grin
The GPMG makes a terrible din - (Sung jimpy)
Early in the morning

Chorus

You hear a bullet whistle by
You see your buddies fall and cry
Behind you there's a final sigh
Early in the morning

Chorus

You see the Harrier over head
And then you see a flash of red
The rockets are gone, the enemy's dead
Early in the morning

Chorus

You look back to the rear and then
You see the choppers coming in
The rising sun's a beautiful thing
Early in the morning

Chorus

They're hovering just above your head
And then they're down and someone said
We'll take the wounded then the dead
Early in the Morning

Chorus

Now look up to the front you men
They'll come again, you know not when
The rising sun's a beautiful thing
Early in the morning

Chorus

The mortar bombs are raining down
But you just want to hug the ground
You hear your buddies calling round
Early in the morning

Chorus

Your plane is flying far away
You know you're homeward bound today
It's sad so many had to pay
Early in the morning

Chorus

You're on the street
You're walking tall
You turn to hear the people call
You've made the grade, you've done it all
Early in the morning

Chorus
