Hi - I don't think Nils's Sleepwalk is right (sorry mate!) Here's my tab of it from beginning to end (including, I think, the right number of D chords). Chords are in CAPITALS/single notes in lower case:

Single notes:

a# c d c a f a
Chord at end: A

Single notes throughout next section (played on synth on the LP):
a# a e f g e d
a# a e f g e d
e d c# a c# d e e d
e d c# a c# d e e d
a# a e f g e d
a# a e f g e d

And chords throughout same section:

play out (single notes)
a# a e f g e d
repeat until end

The only bit I have any doubts over are the first F & E chords in the middle eight. Otherwise it sounds spot on.

Enjoy!
