Travis - Definition Of Wrong tab

Travis: Definition of Wrong
Tuning: Standard (EADGBe)

I had to tab this because it's such a great B-Side! It's the same chords throughout the 
song, this is what I got:

E, B, Bb, A
[ Tab from: http://www.guitaretab.com/t/travis/96167.html ]
It's easy enough to know where to place them.
I think this might be the lead that is played over the B, Bb and A chords:

---7/6---6/5---5/4---------------|
---7/6---6/5---5/4---------------|
---8/7---7/6---6/5---------------|
---------------------------------|
---------------------------------|

Not 100% sure so leave me a comment if u have another suggestion.
Enjoy and please rate.
