Ferry Me Across The Water

'Ferry me across the water,
Do, boatman, do.'
'If you've a penny in your purse
I'll ferry you.'
'I have a penny in my purse,
And my eyes are blue;
So ferry me across the water,
Do, boatman, do.'
'Step into my ferry-boat,
Be they black or blue,
And for the penny in your purse
I'll ferry you.'
