Well, I jsut realized there are multiple solos. I think it's the second one (it's really fast) and it sort of looks like John is pushing one string out of the way and hitting the other ones. From about 4:00-4:30
Just let the good times roll.
yea it looks like hes bending the b string then after the bend plays a hammer on on the e string and repeats. i do that a lot too. the part he plays after which includes his pinky im not completely sure on. i think hes lifting up his index to ring the open note after the other notes.
