this is a really good song, i dont know if its the same as the
origional, because i tabed it from the tall paul version:

the chords are played on eithr guitar or piano

they are:

      Am               F F7 F
dont ask me what you know is true

D D7 D                  F                       F7
dont have to tell me i love your precious heart


with that then play this bass riff:

A)-0-3-5-0-

thats it

enjoy:o)
