I can't produce a reliable summary here — the "article text" you've pasted only contains site navigation and menu items (Music/Film/Travel/Art/News, Shop, Mailing List, "Cover Story | Yard Act"), not any actual content about Lily Allen's tour. No details about the downsizing, reasons, dates, or venues are present in the text provided.

Could you paste the actual body text of the article, or let me know if you'd like me to try fetching the page directly?
