E                 A   B             E
  All through my life I've been hearing
              A    B         E    E/D#
  All about those good old days
C#m         C#m7
  It makes no diff'rence
C#m6           A
  What was or what may be
E            A/C#  Am/C
  Past it is gone
E                A/C#      Am/C
  And future may not be at all
E            A/C#      B/D#   E     A   B
  Present improve the flying hour

  Some people look into the future
  They're hoping that they'll see better days
  It's such a sweet thought
  It's something that could be, but

  Past it is gone
  And future may not be at all
E            A/C#      B/D#   E
  Present improve the flying hour

BRIDGE:
F#m                  D
  What was and what may be
  A
  Is not here,
     E                F#m
  It is not clear to me.
                   D
  Right now is the one thing
       A
  That I can feel
      E                  F#m
  The one thing real to me... ooohh

  So as you sit back to remember
  That which you can not recall
  It makes no diff'rence
  What was or what may be

  Past it is gone
  And future may not be at all
  Present improve the flying hour.
