I heard a record of this song by Paul Robeson and he changes some little things (Songs Of Free Men: A Paul Robeson Recital)
He sings it this way:

MAH LINDY LOU
Words and music by Lily Strickland (1920)

1. Honey, did you hear that mockin’bird sing last night?
O Lord, he was singin’ so sweet in the moonlight,
In that old magnolia tree,
Bustin’ his heart with melody.
I know he was singin’ of you,
Mah Lindy Lou, Lindy Lou.
O Lord, I’d lay right down and die
If I could sing like that bird sings to you,
Mah little Lindy Lou.

2. Lindy, did you smell that honeysuckle vine last night?
O Lord, it was smellin’ so sweet in the moonlight,
Clingin’ ’round my cabin door.
Reckon it’s ’cause he loves it so.
Honey, that’s the way I love you,
Mah Lindy Lou, Lindy Lou.
O Lord, I’d lay right down and die
If I could be as sweet as that to you,
Mah little Lindy Lou.

3. Lindy, did you feel that south wind blow last night?
Honey, it was kissin’ you sweet in the moonlight,
Blowin’ from that old bayo’.
Seemed to say it loves you so.
Honey, that’s the way I love you,
Mah Lindy Lou, Lindy Lou.
O Lord, I’d lay right down and die
If I could be that wind a-kissin’ you,
Mah little Lindy Lou.

Thank You very much. I was looking for those lyrics for three days and found it here. My mother is asking me to put her old longplays to mp3 so I'm looking for the lyrics also to make a good job!
