Song playing as he entered: There Goes My Hero by the Foo Fighters.

Lyrics:

Too alarmin' now to talk about.
Take your pictures down and shake it out.
Truth or consequence, say it aloud.
Use that evidence, race it around.
… There goes my hero.
Watch him as he goes.
There goes my hero. He's ordinary.
… Don't the best of them bleed it out.
While the rest of them peter out?
Truth or consequence, say it aloud.
Use that evidence, race it around.
… There goes my hero.
Watch him as he goes.
There goes my hero.
He's ordinary.
… Kudos, my hero.
Leavin' all the best.
You know my hero.
The one that's on.
… There goes my hero.
Watch him as he goes.
There goes my hero.
He's ordinary.
… There goes my hero.
Watch him as he goes.
There goes my hero.
He's ordinary.
