The article text supplied for this piece did not load correctly — it consists only of website navigation elements (menu links such as "Music", "Film", "Travel", "Art", "News" and a "Cover Story" tag) rather than the actual body of the piece about which song topped the UK charts on the day Live Aid took place in 1985. As a result, there is no substantive article content available to summarise accurately.

Without the genuine text, it would not be responsible to state which song was number one, as doing so risks presenting an unverified guess as fact. A reliable summary would require the actual article content or a working link to the source page.
