VERSE:
        A                    D       A
Little Molly don’t go down to the river
         A           E           A
you’re safely tucked up in your bed
       A                      D  Bm
sweetheart stay away from the water
            A             E             A
‘cause it longs for your pretty blonde head

Little Molly don’t go down to the river
oh darling whatever you do
just stay away from the water
‘cause the tides have been calling for you

CHORUS:
D         A
oh, some places a child shouldn’t go
D        A                         E
oh, some things a child shouldn’t know
A                                   D  A
like the wiles of a handsome young stranger
         A           E           A
or the ways of those closest to home

VERSE:
there’s a darkness runs deep precious one
deeper than you’ll ever know
like the reeds that await the unwary
‘neath the stillest of waters below

CHORUS

VERSE:
listen you’ll hear a voice whisper,
“Come, lay down beside me.”
And it’ll never have peace my sweet daughter
‘till it carries your virtue to sea

D         A
oh, some things are better unsaid
D        A
oh, some stories just shouldn’t be read
D        A                       E
oh, some dreams are too real to forget

VERSE:
dear heart stay away from the water
let your sister take your place instead
Little Molly my prettiest daughter
let your sister go on now ahead
