Putting Bertie at the end of Burlington (as in Burlington Arcade) may suggest the music hall song which begins: "I'm Burlington Bertie, I rise at ten thirty ..."
I know this to be true because I read it in a Morecambe and Wise's autobiography.
What? Yes, yes, I know than Dan's aunt is more likely to be Agnes than Agatha. I only said it may call to mind the Wodehouse character, didn't I?
