From the wiki: “Composed and first recorded by Malcolm Endsley, ‘Singing the Blues’ holds a unique record in the UK: It was the first and, in half a century and more of its existence, the only song in the history of the UK Singles chart to knock itself off the top spot twice! Guy Mitchell’s version topped the UK Singles chart at the start of January 1957, and was replaced the following week by the Tommy Steele version. The following week, the Mitchell version again replaced the Steele version at #1.
