Chord/Tab song: So Glad You're Here

Okay, so the one tricky thing in this song is the opening which goes back and
forth between a C and some kind of crazy diminished chord. I don't know what it
is exactly, but I play it as (low to high) x4301x and have named it a Csus4/C#
below. Sounds close enough to me.

[C]Nothing a[Csus4/C#]bout us looks good on[C] paper[Csus4/C#]
[F]But paper's n[Em]o good in the middle of th[Am]e night
[Dm]So glad you'r[G]e here
[Dm]So glad[G]

People do all the wrong things for the right reasons
Somehow you understand this
So glad you're here
So glad

[F]The more I lose
[Em]The more I know that
[Am]Now is really all we have
[F]Now is all we have[C]

I remember the day you were born
I wasn't read y; I was scared
So glad you're here
So glad
