Who wrote the collingwood theme song?

Answer 1

From the official Collingwood website:

Good old Collingwood forever,

we know how to play the game.

Side by side we stick together,

to uphold The Magpies name.

Hear the barrackers a shouting,

as all barrackers should,

Oh, the premiership's a cakewalk

For the good old Collingwood.

Answer 2

According to the book 'Kill for Collingwood' Tom Nelson, a young player recruited from Williamstown, supplied the words in 1906 to the tune of 'Goodbye Dolly Gray' - a Boer War marching song.
