a chord from Andy

A question for Andy... I play guitar in a cover band and would like to know what the 4th chord (inversion/fingering) you are playing is during the chorus?  ie. right after "I'm on the hunt I'm after you".  The bass is playing Bflat, are you staying on F or is it Bflat sus. 2nd?  I know this is not interesting to some people but it would greatly help me out.
Thanks. Dave

"The actual chord is just a straight Bflat, but I guess I am prone to playing a sus2 live which is a little cleaner. AT"
