Ronnie B gets my vote over Roy because he was the supreme actor who could portray such a variety of characters and of course as a Gerald Wiley wrote many things as he did as Ronnie B .
As an aside I remember Ronnie B was incensed when this came around and he refused to even acknowledge the "new generation" of comedians , I have heard Ben Elton interviewed about his relationship with Ronnie B and how toxic it was .
