could this be the hardest bendy bit?

Hi all
something for the advanced Players I think.

I am obsessed with nailing the Solo from Pink Floyds "another brick in the wall pt 2" and have posted below a bar of the tab from the middle of the solo. I have managed to learn to play most of the solo fairly competently but the bit I have most difficulty is the huge bending bit. I recommend you listen to it if you dont know it, its a superb bit of guitar playing but that bend which changes pitch about 3 times is just incredible and so darned hard to do !
basically he takes the B string at 13, bends it up to 15, then bends it up to 17 holds a moment, up to 18 (yup a 4 fret bend) then slowy releases to 15 and back up to 17 - all the time maintaining the volume...how the heck does he do it?...I have listened to it slowed right down and I swear he re-picks at least twice but others say not?....when I try to play it, all power(volume) has gone out of the bend by the time I get to the top of the bend so there is nothing volume wise left when trying to slowly release it back down.
Please, if you get chance listen to it, try it and tell me what you think and how to acheive the sound.
