This song has been mentioned at Mudcat before, in the thread called Songs for Apple Day:

Bob Kenward of Kent has written a superb song about different varieties of apple. It starts off

'Good apple, she's my heart's delight,
I'll pick no peach or pear,
And pippin she's the queen of all
And that I do declare'.

I think you could find him by Googling on Kent Folk. He's a good singer and writer of songs in the traditional style.

That's all it says.
