Here's how it goes...
D7sus-F7sus- repeat x4
Eb7sus-Db7sus- repeat x1
D7sus-F7sus- repeat x3
Eb7sus-Db7sus- repeat x1
D7sus-F7sus- repeat x3
Eb7sus-Db7sus- repeat x1
D7sus-F7sus- repeat x3
At least I'm pretty sure that's it. It doesn't seem that difficult to me because all the chords are of one variation, you just move that shape around.
Now that I've said that I hope I can come up with something that doesn't suck.
