From about 1917, Who's Who in the Theatre, including a section devoted to "variety,"
has a short entry for songwriter Frank Leo.

I did look online for sheet music for Frank Leo songs.
"Come Up in My Balloon" is the only one I can find.
But reading the Who's Who article leads to the conclusion
that this 'peculiar thing' piece is a song,
for all that the music is not to be found in online searches.
Let me see how well I can reproduce this entry here.

LEO, Frank, lyricist, composer and entertainer;
born Chatham, 10 Sept. 1874;
son of Vincent Gregory Peers and his wife Cordelia (Holmes);
married Sable Fern [you don't say?!];
was formerly engaged as a fine arts decorator;
for many years was popularly known as
the writer and composer of hundreds of songs,
and especially of those sung by Wilkie Bard,
which helped to form that artist's peculiar style;

Among the songs which he composed for that artist may be mentioned:

I Fell Off the 'Bus
Do You Know Any More Funny Stories?
I Wish I'd Bought Ducks
That's Where She Sits All Day
There's A Peculiar Thing
Is There Anything Else You'd Like?
I'd Like To Go Halves in That
I Think We Shall Have Some Rain
Has Anyone Seen Our Cat?
I'm Not Such a Goose as I Look
You, You, You!
One and a Penny a Day
The Night Watchman
The Cowslip and the Cow
My Little Deitcher Girl
Let Me Sing
When the Bugle Calls   
etc.

After twenty years of writing for others,
decided to appear on the stage himself,
and made his first appearance on the music-hall stage at
The Palace, Bath, March 1915, singing his own songs;
first appeared in London at
The Bedford, Camden Town, 3 May, 1915.


(It seems the songwriter was still alive when this was published.)
