MAH LINDY LOU
Words and music by Lily Strickland, ©1920.

1. Lindy, did you heah dat mockin’bird sing las’ night?
Honey, he wuz singin’ so sweet in de moonlight!
In de ol’ magnolia tree,
Bustin’ his heart wid melody!
I know he wuz singin’ ob you,
Mah Lindy Lou, Lindy Lou!
I’d lay right down an’ die, an’ die,
Ef I could sing lak dat bird sings to you,
Mah liddle Lindy Lou!

2. Lindy, did you smell dat honeysuckle vine las’ night?
Honey, he wuz smellin’ so sweet in de moonlight!
Clingin’ ’roun’ ma cabin do’,
Reckon it’s ’cause he loves hit so!
Honey, dat’s de way I love you,
Mah Lindy Lou, Lindy Lou!
I’d lay right down an’ die, an’ die
Ef I could be as sweet as dat to you,
Mah liddle Lindy Lou!

3. Lindy, did you feel dat souf win’ blow las’ night?
Honey, hit wuz kissin’ you sweet in de moonlight!
Blowin’ from de ol’ Bayou,
Seemed to say hit love you so!
Honey, dat’s de way I love you,
Mah Lindy Lou, Lindy Lou!
I’d lay right down an’ die, an’ die,
Ef I could be dat win’ a-kissin’ you,
Mah liddle Lindy Lou!
