I found this in a text file from 2010, to the tune of Bowling for Soup's 1985:
He was gonna be a Spectre!
He was gonna be a star!
He was gonna dance all night,
And down shots in Flux's bar!
His AI'd Normandy is now the enemy.
Looks at his abnormal life,
And nothing has been all right since:
Sovereign, Sha'ira,
Way before Samara,
There was Saren and Jenkins,
And talking still on elevators...
Programs on his omnitool
They tell him that he's uncool,
Cause he's all preoccupied
With 21, 21, 2185...
