You can hear Harry Champion singing this at YouTube or The Internet Archive. I listened, and made these corrections, in boldface, to the lyrics posted by Sorcha above:

A LITTLE BIT OF CUCUMBER
Written by T. W. Connor, 1915
As recorded by Harry Champion, 1915

1. Now, I was weaned on cucumber, and on my wedding day,
When the fun was over and the guests had gone away,
My old darling said to me, "You must be hungry, Joe.
Is there anything you fancy?" I said, "Fancy! Don't you know?"

CHORUS: "I like pickled onions. I like piccalilli.
Pickled cabbage is all right
With {a bit of cold meat}* on Sunday night.
I can go tomatoses, but what I do prefer,
Is a little bit of cucum-, {cucum-, cucum-}**, little bit of cucumber."

2. I went flying through the air with my old college chum.
Suddenly he said to me, "We're bound for kingdom come!
Have you anything on your brain before you wear a crown?"
I began to shake and said, "Write this confession down: CHORUS

3. Sev'ral years of married life have brought me lots of joys.
I don't know how many girls, I think there's fourteen boys.
When the last one came to town, it fairly turned my head.
He was marked with a cucumber, and the first words that he said
Was: CHORUS

4. To the Lord Mayor's banquet, I went in one foggy day.
When I saw the grub, it took my appetite away:
With "Sparrowgrass" and chaffinches, and pig's-head stuffed with jam!
I said, "I don't care for that. You don't know who I am!" CHORUS


* On some repetitions of the chorus, substitute "a bit of cold tripe" or "bubble and squeak."

** On some repetitions of the chorus, substitute "cummy-cum-cum-cum" or "I come, you come."
