Already common knowledge but for those of you who don't know it:

Across the Field
Fight the team across the field,
Show them Ohio's here
Set the earth reverberating with a mighty cheer
Rah! Rah! Rah!
Hit them hard and see how they fall;
Never let that team get the ball,
Hail! Hail! The gang's all here,
So let's win that old conference now.

Buckeye Battle Cry
In old Ohio there's a team
That's known thru-out the land;
Eleven warriors, brave and bold,
Whose fame will ever stand.
And when the ball goes over,
Our cheers will reach the sky,
Ohio field will hear again
The Buckeye Battle Cry-

Drive! Drive on down the field,
Men of the scarlet and gray;
Don't let them thru that line,
We have to win this game today,
Come on, Ohio!
Smash through to victory.
We cheer you as you go:
Our honor defend
So we'll fight to the end for O-hi-o.

Alma Mater: 

Carmen Ohio
Oh! Come let's sing Ohio's praise,
And songs to Alma Mater raise;
While our hearts rebounding thrill,
With joy which death alone can still.
Summer's heat or Winter's cold,
The seasons pass, the years will roll;
Time and change will surely show
How firm thy friendship O-hi-o.

These jolly days of priceless worth,
By far the gladest days of earth,
Soon will pass and we not know,
How dearly we love O-hi-o.
We should strive to keep the name,
Of fair repute and spotless fame,
So, in college halls we'll grow,
To love the better, O-hi-o.

Tho' age may dim our mem'ry's store,
We'll think of happy days of yore,
True to friend and frank to foe,
As sturdy sons of O-hi-o.
If on seas of care we roll,
'Neath blackened sky, o'er barren shoal,
Tho'ts of thee bid darkness go,
Dear Alma Mater O-hi-o.
