Notre Dame Victory March
Of course this is a classic and everyone has heard it before. What I like most about it is that during the main part of it (the trio?), it says much more than most fight songs. Usually, we just hear things like "we will win. we are great", but the Victory March asks to "wake up the echos" and "shake down the thunder." They recognized tradition way back in 1908. Nice.
Cheer, cheer for old Notre Dame,
Wake up the echoes cheering her name,
Send a volley cheer on high,
Shake down the thunder from the sky.
What though the odds be great or small
Old Notre Dame will win over all,
While her loyal sons are marching
Onward to victory.
