. . . when the boat comes in

Dance to your Daddy, my little laddie
Dance to your Daddy, my little man
Thou shalt have a fish and thou shalt have a fin
Thou shalt have a codlin when the boat comes in
Thou shalt have haddock baked in a pan
Dance to your Daddy, my little man

Dance to your Daddy, my little laddie
Dance to your Daddy, my little man
When thou art a young boy, you must sing and play
Go along the shore and cast your shells away
Build yourself a castle, watch the tide roll in
Dance to your Daddy, my little man.

Dance to your Daddy, my little laddie
Dance to your Daddy, my little man
When thou art a young man, go unto the trades
Find yourself a skill, and wages you’ll be paid
Then with all your wages, buy yourself some land
Dance to your Daddy, my little man

Dance to your Daddy, my little laddie
Dance to your Daddy, my little man
When thou art a man and go to take a wife
Find yourself a lass and love her all your life
She shall be your wife and thou shalt be her man
Dance to your Daddy, my little man

Dance to your Daddy, my little laddie
Dance to your Daddy, my little man
When thou art an old man, father to a son
Sing to him the old songs, sing of all you've done
Pass along the old ways, then let his song begin
Dance to your Daddy, my little man

Come here, maw little Jacky
Now aw've smoked me baccy
Let's hev a bit o'cracky
Till the boat comes in

Chorus: Dance ti' thy daddy, sing ti' thy mammy,
Dance ti' thy daddy, ti' thy mammy sing;
Thou shall hev a fishy on a little dishy,
Thou shall hev a fishy when the boat comes in.

Here's thy mother humming,
Like a canny woman;
Yonder comes thy father,
Drunk---he cannot stand.

Chorus: Dance ti' thy daddy, sing ti' thy mammy,
Dance ti' thy daddy, ti' thy mammy sing;
Thou shall hev a fishy on a little dishy,
Thou shall hev a haddock when the boat comes in.

Our Tommy's always fuddling,
He's so fond of ale,
But he's kind to me,
I hope he'll never fail.

Chorus: Dance ti' thy daddy, sing ti' thy mammy,
Dance ti' thy daddy, ti' thy mammy sing;
Thou shall hev a fishy on a little dishy,
Thou shall hev a bloater when the boat comes in

I like a drop mysel',
When I can get it sly,
And thou, my bonny bairn,
Will lik't as well as I.

Chorus: Dance ti' thy daddy, sing ti' thy mammy,
Dance ti' thy daddy, ti' thy mammy sing;
Thou shall hev a fishy on a little dishy,
Thou shall hev a mackerel when the boat comes in.

May we get a drop,
Oft as we stand in need;
And weel may the keel row
That brings the bairns their bread.

Chorus: Dance ti' thy daddy, sing ti' thy mammy,
Dance ti' thy daddy, ti' thy mammy sing;
Thou shall hev a fishy on a little dishy,
Thou shall hev a salmon when the boat comes in.
