Chord/Tab song: Used To

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
We had nowhere we needed to [Bb]go,
Nice and slow, to[Bb] no place in [C]particular.

Chorus:
[F]We used to have this figured out;
[C]We used to breathe without a doubt.
W[Bb]hen nights were clear, you were the fi[C]rst 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
