Learning how to

I was just cast as Dennis in a local production of All Shook Up. I'm really excited about the role and look forward to taking on it's challenges. However, there is one problem. Dennis is a tenor, I am a baritone. This role is very demanding for even a tenor. The highest note he has to hit (which he just pops once or twice) in the show is a B (Bb?) in his song "It Hurts Me." I've only had a year and a half of formal vocal training, and I have a G (comfortably) in my chest voice, a G# is pushing it a little, but I have one nonetheless. My question is, do you think it will be possible for me to learn how to pop that B (or Bb if that's what it is, I can't recall right now) in about three months?

The title says "learning how to belt" because I've never learned how to belt before (never had to) and I assume that's what I will need to do in order to achieve this goal.

Thanks for the tip. I've always had trouble with placement, but I just attempted to sing up the scale placing the sound towards the back of my head (like you recommended) and I got up to an A, which is only a half-step short of the Bb, however it was a little weak and "breathy". I'll play with it and see what I can do. Thanks again.
