You picked a good teacher in Dave Gilmour, the man can bend a string like no other. As for easy Floyd songs most of breathe is Em9 and A. strum the the Em9 from high E to bottom, if you want the fills i'll tab 'em for you but it might take a while.
The intro of in the flesh is based on the Em scale in 12/8 time
then inverted 5ths
then the fill is
bend the 1st, 5th and 9th notes of the fill 1 full step and the 17 a half step. I was going to tab bits of the wall solo to show you the string bends but i just found out i cant notate them in this. if you want the tab i will scan and email it to you if you want. good luck
