The sheet music:
Accompaniment by James Pitt-Payne:
Lyrics
I want to testify
I’ll get no rest, if I
Don’t make a start to tell
What’s in my heart, to tell you
Don’t try to guess
But hear me through
Then answer yes
Burthen
You will now, won’t you?
You will, won’t you?
You want to, don’t you?
You do, don’t you?
Eventually, content you will be
If only you don’t keep her lonely
Just give a thought to
What you ought to
Don’t say ought not to
You’ve just got to
Because I cannot marry you
Unless you marry me, too
