Diddy or Diddny?

Many moons ago, Nick Waterfall, who is a very courteous engineer friend of mine, notoriously uttered these very English words:

Would you like a cup of tea Mr Dogg?”

To the rap artist, Dirdy Ole Dogg.

A bit like how Dave Wrong just loves to call blues hobo Vertigo Vince, “Verty”.

I am excited, because I’ve heard from Nick that he is recording a session with rapper Diddy Do Dat today. He is wondering whether to try and introduce him to vintage joke band Do Wah Diddy and the Doddymen, who Mr Diddy will almost certainly not be aware of.
