Help on WB adjustment

I recently did shoot some pictures of a friend's wedding using a canon 5D2.

However, I shot JPG and left the WB to auto and the pictures turn out to the all yellow!

I do have some experience in adjusting color in CS4 (either by using auto-level / auto-color or playing with manual color balancing), and usually have acceptable result.

However this time the color has gone way to yellow and I can't get the color back to a more natural state.

Do you mind to try adjusting the color of this photo and let me know what adjustment setting you use?

Help would be appreciated.
