Yesterday, the Covenant fleet seemed so far away
Now it looks as if they'd like to play
Oh, Earth was safer yesterday.

Suddenly, I'm twice the SPARTAN that I used to be,
With an AI hanging out with me.
Oh, yesterday came suddenly.

Why she had to go I don't know she wouldn't say.
I shot something wrong, now I long for yesterday.

Yesterday, Halo 1 was such an easy game to play.
Now from the Flood I need to hide away
I should've stood in bed yesterday.

Mm mm mm mm mm.
