From the sheet music at The National Library of Australia. Only a few words are different from those posted above, so I have boldfaced them.

DOLLY GRAY
Words, Will D. Cobb. Music, Paul Barnes.
Melbourne : Allan & Co., c1900.

"Sung by the Tobins and Maggie Moore".

1. I have come to say goodbye, Dolly Gray.
It's no use to ask me why, Dolly Gray.
There's a murmur in the air.
You can hear it ev'rywhere.
It is time to do and dare, Dolly Gray.
Don't you hear the tramp of feet, Dolly Gray,
Sounding through the village street, Dolly Gray?
'Tis the tramp of soldiers' feet
In their uniforms so neat,
So goodbye until we meet, Dolly Gray.

CHORUS: Goodbye, Dolly. I must leave you,
Tho' it breaks my heart to go.
Something tells me I am needed
At the front to fight the foe.
See the soldier boys are marching
And I can no longer stay.
Hark! I hear the bugle calling.
Goodbye, Dolly Gray!

2. Hear the rolling of the drums, Dolly Gray.
Hark from war the reg'ment comes, Dolly Gray.
On your lovely face so fair
I can see a look of care
For your soldier boy's not there, Dolly Gray.
For the one you loved so well, Dolly Gray,
In the midst of battle fell, Dolly Gray.
With his face towards the foe,
As he died, he murmured low,
"I must say goodbye and go, Dolly Gray."
