The prelude included in the front has always been Fmaj7-G-Em7-Am.
Chorus (I miss you so much. . . I miss you so much. . )Fmaj7-G-Cmaj7
I still miss you on tiptoe. . . That part is Am-F-Am-F alternating.
That's basically it. Bake the rest yourself.
This song is not difficult. The melody is basically an inner chord.
I just type and say chords.
