hope your tab source is a good one..so many of those tab charts are homogenized versions and don't sound a lot like the record (assuming that's what you are going for) ... the 'hook' (the signature riff in that tune) is so important to that song i can't imagine even the most amateur of tabsters getting it wrong, though.

Still like to learn it right off the record by ear whenever possible though...and vary it according to taste - or not.
