When you play Am7 during the verses, omit the 5th. For the G7 chord on "once there was a way", omit the 5th. Verse

^Am7Once there was a way to get back ^Dmhomeward ^G7Once there was a way to get back ^Chome

^E7Sleep pretty ^Amdarling do not ^Dm9cry ^G7And I will sing a lulla^Cby

Chorus

^CGolden ^Fmaj9slumbers fill your ^Ceyes ^CSmiles ^Fmaj9awake you when you ^Crise

^ESleep pretty ^Amdarling do not ^Dm9cry ^G7And I will sing a ^Clullaby

Verse

^Am7Once there was a way to get back ^Dmhomeward ^G7Once there was a way to get back ^Chome

^ESleep pretty ^Amdarling do not ^Dm9cry ^G7And I will sing a lulla^Cby

Ending there sounds fine, but the real song goes straight into "Carry That Weight".
