For some reason, everyone is tonedeaf. The song is obviously played in the key
of A, I have posted it up here.

    A (x02220@1)                      B (x2444x@1)    Those school girl days
                D (xx0232@1)                        A (x02220@1)    of telling tales and biting nails are gone
   A (x02220@1)              B (x2444x@1)    But in my mind
                 D (xx0232@1)                       A (x02220@1)    I know they will, will still live on and on

     G#m (133111@4)               C#m (x13321@4)        But how do you thank someone
                 G#m (133111@4)                      C#m (x13321@4)        who has taken you from crayons to perfume
       B (x2444x@1)        E (022100@1)           B (x2444x@1)    F# (244322@1)        It isn't easy but I'll try....

            B (x2444x@1)    If you wanted the sky
         D (xx0232@1)                     B (x2444x@1)    I'd write across the sky in letters
                D (xx0232@1)                  B (x2444x@1)    that would soar a thousand feet high
        E (022100@1)       F# (244322@1)

     A (x02220@1)                   B (x2444x@1)       The time has come
                 D (xx0232@1)                           A (x02220@1)    for closing books and long last looks must end
     A (x02220@1)             B (x2444x@1)    And as I leave
                 D (xx0232@1)                   A (x02220@1)    I know that I am leaving my best friend

     G#m (133111@4)                      C#m (x13321@4)       A friend who taught me right from wrong
            G#m (133111@4)                            C#m (x13321@4)       and weak from strong, that's a lot to learn
        B (x2444x@1)              E (022100@1)           B (x2444x@1)     F# (244322@1)       What! what can I give you in return

            B (x2444x@1)    If you wanted the moon
     D (xx0232@1)                             B (x2444x@1)    I would try to make a start But I
           D (xx0232@1)                       B (x2444x@1)    would rather you let me give my heart
        E (022100@1)       F# (244322@1)

     A (x02220@1)               B (x2444x@1)       Why is it Sir
                      D (xx0232@1)                  A (x02220@1)       children grow up to be people some day

     G#m (133111@4)                        C#m (x13321@4)       What takes the place of climbing trees

            D (xx0232@1)                      B (x2444x@1)    I'd surround it with a wall I'd scrawl
           D (xx0232@1)                         B (x2444x@1)    These words with letters ten feet tall
