Exactly, Dazed!!! He has to be the best melodic solo player in rock music..maybe ever. I tell all of my guitar students who ask about soloing to learn atleast one David Gilmour solo, it'll do ya good!

I tell them just what you have said, try to sing it, if you can then it will get stuck in the listeners head and then they'll want to hear more. When a guitar solo appeals to the ear as melody, not just fluffy technique, then it goes right to the part of the brain that not only stores, but seems to desire such melodies as heard in Eine Kleine Nacht Music, Amazing Grace, Jingle Bells and yes the solo from Another Brick in the Wall.
