Not much to add,

1 it was 'Nina & Frederik'

2,
"It's (a) long time boy I never see you,
Come Let me hold your Hand boy
Let me hold your hand
It's (a) long time boy I never see you,
Come Let me hold your Hand boy
Let me hold your hand

See that John Crow sit on the treetop,
Pick all the blossoms,
Let me hold your Hand boy
Let me hold your hand

It's a long time boy I never hear you,
Come let me walk & talk boy,
Let me walk and talk,,, etc.,"
