      vaudevillian, Jack Norworth, her 2nd of 5 husbands, with whom she

      the song and. put his wife's name on it. Bayes recorded many times for

verse:

Down below, down below,
sat the Devil talking to his son,
who wanted to go

up above, up above
he said it's getting too warm for me
down here, and so

I'm going up on earth
so I can have a little fun
The Devil only shook his head
and answered his son,

chorus:

Stay down here where you belong,
the folks who live above you
don't know right from wrong
To please their kings
they've all gone out to war
and not a one of them knows what he's fighting for.

Way up above they say that I'm
a devil and I'm bad
kings up there are bigger
devils than your dad.

They're breaking the hearts of mothers
making butchers out of brothers
you'll find more trouble there
than you will down below.

verse:

kings up there, they don't care
for the mothers who must stay at home
their sorrows to bear.

stay at home, don't you roam
though you don't like it below,
you'll find it warmer up there.

If ere you went up on the earth
I know you'de be surprised
you'll find a lot of people
who are not civ il ized.

repeat

Stay down here
where you belong,
the folks who live above you
don't know right from wrong

To please their kings
they've all gone out to war
and not a one of them
knows what he's fighting for.

Way up above they say that I'm
a devil and I'm bad
kings up there are bigger
devils than your dad.

They're breaking the hearts of mothers
making butchers out of brothers
you'll find more trouble there
than you will down below.
