Fact
The most famous rock song of all time, this didn't chart because it was never released as a single to the general public. Radio stations received promotional singles which quickly became collector's items.
On Tuesday November 13, 2007, Led Zeppelin's entire back catalogue was made available as legal digital downloads, making all of their tracks eligible for the UK singles chart. As a result, at the end of that week the original version of "Stairway To Heaven" arrived in the UK singles charts for the first time.
