This song used to reduce me to tears. Here are the chords as I recall them.
(D) Goodbye, (G) mamma. Goodbye to (D) you too, pa.
(E min) Little Sister, you'll have to wait a while to come (G) along.
(D) Goodbye to this (G) house and all its (D) memories.
(E min) We all just got to old to say we're (G) wrong.
(D) Got to (D/C#) make one (D/B) last trip (D/A) to my (G) bedroom.
(D) I guess (D/C#) I'll have to (D/B) leave some (D/A) stuff (G) behind.
(D) It's funny (D/C#) how the (D/B) same old (D/A) crooked (G) pictures
(D) Just don't (D/C#) look the (D/B) same to (D/A) me to- (G) night.
The (D) - (D/C#) - (D/B) - (D/A) is one of those walk downs, a la "Mr. Bojangles". Sorry if I'm stating the obvious, but the note after the slash is the bass note.
I hope that my hard returns keep the phrases intact. I'm really uncomfortable about posting lyrics 'cause they usually end up as one long jumbled paragraph.
