Here's the lyrics:
Glen, Glen Glen Glen
Glen Glen, Glen
Glen, Glen, Glen
Glen's the man, going to work
Got his tie, got ambition
Middle management is right in his grasp
It?s a dream he will never let die
Glen?s the man of the hour, he?s the king of his cube
Status quo report have finally met their rival
Burnin' the candle at both ends on the way to the top
He knows one day he just could become
Supervisor.
Roy, Roy, Roy, Roy
And yeah, it is actually Survivor in the commercial (the singer is also the guy who does the singing for Budweiser's Real American Heroes ads).
