Day is dying in the west
Angels watchin' over me my Lord
Sleep, my child and take your rest
Angels watchin' over me

Now I lay me down to sleep
Angels watchin' over me my Lord
Pray the Lord my soul to keep
Angels watchin' over me

Chorus:

All night, all day
Angels watchin' over me my Lord
All night, all day
Angels watchin' over me
If I die before I wake
Angels watchin' over me my Lord
Pray the Lord my soul to take
Angels watchin' over me

Thanks to Emmeline Stoddart for this extra verse!

If I live for ever and a day
Angels watchin' over me, my Lord
Pray the Lord guard me always
Angels watchin' over me

Thanks to Sarah Wade, who sent me this version of the song. Actually, this is the version that I'm most familiar with too!

Chorus:

All night all day
Angels watching over me my Lord
All night all day
Angels watching over me
As I lay me down to sleep
Angels watching over me my Lord
Pray the lord my soul to keep
Angels watching over me

If I die before I wake
Angels watching over me my Lord
Pray the Lord my soul to take
Angels watching over me

If I live forever and a day
Angels watching over me my Lord
Pray He'll guard my soul always
Angels watching over me
