Hi Frosty,
sadly I don't know that particular song - I borrow a fred hammond DVD from a student of mine a few years back, and loved it, but can't remember the tracks...
have you got a chord chart for the song? That's the first thing - get one of the guys in the band to write them out for you if you haven't got them.
Then, find out if there are any bits of the song where the bass plays in unison with anyone else... if not, you're safe. If there are, get the person playing the line with you to show you how to do it.
Then, LISTEN TO THE DRUMS - start by playing the root of the chord on each kick drum, and build from there. It may be that that's enough. Take it slowly, stay with the groove first and add stuff as it feels right, but err on the side of caution.
Enjoy,
Steve
