Remember that the harmonics will sound best if you are in the treble position. When you get to the double behind the nut bend (starting at 1:30 in the video) remember that you are bending the G up a whole step to A, and simultaneously bending B up a half step to C. This may be tricky at first. If you find it difficult, you may want to spend some time getting each bend on its own. Play the note that you are bending up to and try to nail it with the bend. Once you are comfortable with both bends individually, then try tying them together and concentrate on the B string bend, the other will fall naturally!
