The 2 verses I have are from Doerflinger's Shantymen & Shantboys. Such a great song, I'm hoping for more, what I've got is as follows;

Oh, Jack's come home from from sea today
All brown & bronzed was he
For many years he's been away
From his home across the sea
But his heart's as true as it was of yore
His spirit's light & gay
Little know the joy we felt when he came home today
Chorus
Our Jack's come home today (2x)
The good ship Jane's in port again
Our Jack's come home today

Our Jack's come home from sea today
To make his Nell his bride
With loving heart she ne'er despaired
Though all hope within her died
Her eyes grew dim, her cheeks grew pale
She slowly pined away
All danger's past, he's safe at last
For he came home today
Chorus

Begger's Velvet did a version of the prisoner Jack coming home today but I'm looking for more of sailor Jack, any help? Thanks, Barry
