There's a few tabs / chords on here but I believe
this one is the most accurate for solo guitar
interpretation.
The verses are just G / Dm / C (all open)
the timing is slightly difficult to get right but
listen to the recording to hear the changes.
Then the chorus is C / Bm / G / Em / D / Bm / C
(all open except Bm).
So it goes...
G
Do they
C
know
Bm
those
G
days are
Em
golde...
D
..eee..
Bm
...eeen
C
C
Build A
Bm
rocket boys
G
etc etc etc,
Hope that gives you some idea of how it goes. In
the verses, the Dm to C progression might change
to something else at some point but I can't work
out what exactly. Maintaining the Dm to C change
doesn't stick out too badly (it may even be
technically correct) and only a pedant would
notice in a performance.
Any comments appreciated.
