intro : ~f A# A#/G Cm F# f~

verse :

A# A#/G
all of the astronauts
Cm
champagne in plastic cups
F# F A#
waiting for the big hero to show .
A# A#/G
outside the door he stands
Cm
his head in his hands
F# F
and his heart in his throat .

chorus :

D# A#
what can he tell them now?
D# C
sorry i let you down
D# F A#
sorry it wasn’t quite true .
D# A#
but don’t get hung up on it
D# C
just soldier on with it .
D# F A#
and good luck with shooting the moon .

repeat for other verse and chorus .
enjoy!
