' Meanwhile, the Treasury issued "currency notes" of ten
shillings and rom 1914 to 1928, plus (in 1919 only) notes
for one shilling, half-a-crown (two shillings and six pence), and
five shillings. The signature on the Treasury Notes of 1914 to
1917 was that of John Bradbury, hence the enigmatic name at
the end of some versions of this song:

    "Abe, Abe, Abe my boy - what are you waiting for now?
    You promised to marry me some day in June:
    It's never too late and it's never too soon.
    All the family they keep on asking me,
    which day? what day? I don't know what to say!
    Abe, Abe, Abe my boy - what are you waiting for now?"
    "John Bradbury!"

e.g. with unnamed artiste/s, on Ariel Records # 4068 (78rpm).
"Can you tame wild Wimmen" and "Abe Abe Abe my Boy"
( see for example http://www.guysrugby.com/songs.asp
although this site gives a "rude" parody for the 5th line:
"which day? what day? I'm in the fam'ly way!" )
For anybody who doesn't quite get it, the young man
presumably thought he did not have enough money available
to undertake such a commitment.'
