Daughtry - Used To tab

 hey, I usually don't post tabs, but I noticed everyone posted the song "Used to" as
on an E and I'm not saying thats wrong, because maybe its completely right. However, I was
Daughtry perform this song on AOL Sessions and it looks to me like he starts it off on 
F chord. Take this for what you will, but from listening to it and watching him play, I
the chords are F Bb C

Verse1:
F
You used to talk to me like

I was the only one around.
Bb
You used to lean on me like

The only other choice was falling down.
F
You used to walk with me like
                            Bb
We had nowhere we needed to go,
                 Bb           C
Nice and slow, to no place in particular.


Chorus:
F
We used to have this figured out;
C
We used to breathe without a doubt.
 Bb                                    C
When nights were clear, you were the first star that I'd see.
F
We used to have this under control.
?
We never thought.
           ?
We used to know.

At least there's you, and at least there's me.

  sorry, its not complete, I haven't been able to figure it all out yet, but based on
people think, I can add more later. if
