Ok, this is the all acoustic version of Terrapin that David Gilmour played live at the 
Concert.
The video is on YouTube so you can look at that to see how he does it.

For some of the chords he uses basically half of a standard bar cord to free up his 
for a
little lick he does with a few of them.  Here's how all the chords look:

E   022100
G   xx5433
A   xx7644
D   xx0775
E   x7675x
C   xx10988
G#  xx6544
A#  xx8766

Here's how it goes.  The muted notes shown as x's can vary as you can play the song throwing
them on various beats, so don't focus on exactly how I have it typed out.  Like I said look
up the video of David Gilmour doing this on YouTube to see how he does it. Enjoy!
Its really not that hard at all.

Solo: he basically plays the same stuff as before but adds a few little licks in there
instead of the regular chords.  You should be able to figure out the rest, he just goes
through the first verse again and then ends strumming the A.

Thanks!
