[Dave, Melbourne,Australia]

That went over well!

I believe it was the first 4 stanzas and the final stanza:

There was a time in this fair land when the railroad did not run
When the wild majestic mountains stood alone against the sun
Long before the white man and long before the wheel
When the green dark forest was too silent to be real

But time has no beginnings and hist'ry has no bounds
As to this verdant country they came from all around
They sailed upon her waterways and they walked the forests tall
And they built the mines the mills and the factories for the good of us all

And when the young man's fancy was turnin' to the spring
The railroad men grew restless for to hear the hammers ring
Their minds were overflowing with the visions of their day
And many a fortune lost and won and many a debt to pay

For they looked in the future and what did they see
They saw an iron road runnin' from sea to the sea
Bringin' the goods to a young growin' land
All up through the seaports and into their hands

For there was a time in this fair land when the railroad did not run
When the wild majestic mountains stood alone against the sun
Long before the white man and long before the wheel
When the green dark forest was too silent to be real
When the green dark forest was too silent to be real
And many are the dead men too silent to be real.

So, not quite the fast-slow-fast trilogy, but an excellent condensed version for the half-time showpiece at a huge national sporting event. Those young musical acts would have been in awe at the no-frills-needed performance and audience response to a 74-year-old who has captivated Canada and other countries for 5 decades.
