Seventeen Come Sunday as sung by Harry Cox, (1885-1971) of Catfield, Norfolk (no date given but recorded first in 1956).
This is the version I prefer to the one above...and used to sing once....

-----------------------------------
As I walked out one May morning,
One May morning so early'
I overtook a pretty young maid,
Just as the sun was rising,
CHORUS: With my ru, dum, day, fol la diddle day,
Whack with your fol-lad diddle die -do.

Where are you going my pretty maid,
Where are you going my honey?
She answered me right cheerfully,
"In an errand for my mommie."
CHORUS

O, her stockings were white, her shoes were black,
And her buckles shone like silver,
She had a dark and a rolling eye,
And her hair hung round her shoulders.
CHORUS

"How old are you my pretty fair maid,
How old are you my honey?"
She answered me right cheerfully,
"I am seventeen come Sunday."
CHORUS

"Will you marry me my pretty fair maid,
Will you marry me my honey?"
She answered me right cheerfully,
"I dare not for my mommie."

"If you come down to my mammy's house,
When the moon shines bright and clearly,
And I'll come down and let you in,
And my mommie will not hear me."

"I went unto her mammy's house,
When the moon was bright and clearly,
She came down and let me in,
And her mommie did not hear her.
