Here are the lyrics Snuffy linked to. I've wondered about this song for a long time. It seems that Snuffy has given us the key.
So, who's Leslie Sarony?

AIN'T IT GRAND TO BE BLOOMING WELL DEAD!
(Leslie Sarony)

Lately there's nothing but trouble, grief and strife.
There's not much attraction about this bloomin' life.
Last night I dreamt I was bloomin' well dead.
As I went to the funeral, I bloomin' well said:

Look at the flowers, bloomin' great orchids.
Ain't it grand, to be bloomin' well dead!
And look at the corfin, bloomin' great 'andles
Ain't it grand, to be bloomin' well dead.
I felt so 'appy to think that I'd popped off.
I said to a bloke with a nasty, 'acking cough:
Look at the black 'earse, bloomin' great 'orses
Ain't it grand, to be bloomin' well dead!

Look at the bearers, all in their frock coats
Ain't it grand, to be bloomin' well dead!
And look at their top 'ats, polished with Guinness
Ain't it grand, to be bloomin' well dead!
Some people there were prayin' for me soul
I said, 'It's the first time I've been off the dole'
Look at the mourners, bloomin' well sozzled
Ain't it grand, to be bloomin' well dead!

Look at the children, bloomin' excited
Ain't it grand, to be bloomin' well dead!
Look at the neighbours, bloomin' delighted
Ain't it grand, to be bloomin' well dead!
'Spend the insurance', I murmered, 'for alack
'You know that I shan't be with you going back.'
Look at the Missus, bloomin' well laughing
Ain't it grand, to be bloomin' well dead!

Look at me sister, bloomin new 'at on
Ain't it grand, to be bloomin' well dead!
And look at me brother, bloomin' cigar on
Ain't it grand, to be bloomin' well dead!
We come from clay and we all go back they say
Don't 'eave a brick it may be your Aunty May
Look at me Grandma, bloomin' old haybag
Ain't it grand, to be bloomin' well dead!
