Liverpool have apologised after the club's official Twitter account send a tweet appearing to mock the Munich air disaster.
Liverpool initially sent a tweet asking fans to to suggest a three-song playlist to be played at Anfield on Sunday when the Reds host Manchester United.
And one response to the tweet was: 'Come Fly With Me' by Frank Sinatra, 'Always Look on the Bright Side of Life' by Eric Idle and 'I Like to Move It' by Reel to Reel.
These songs had previously been adapted by some fans, who have been known to chant: 'Always Look on the Runway for Ice' and I Like to Munich, Munich'.
And, to the shock of many, Liverpool's Twitter account @lfc responded to the tweet, saying: "Have you been sneaking a look at the dressing room iPod?"
After deleting the tweet and forming an internal investigation, Liverpool issued a statement of apology to the Manchester Evening News, saying: "Liverpool Football Club responded quickly to correct the error of judgement that was made last night on it's official Twitter account in responding to a distasteful and inappropriate Tweet. The Club took decisive action and the comment was deleted swiftly.
"We apologise, unreservedly, for any offence that was caused by this mistake."
The 1958 tragedy saw eight Manchester United players and 15 others die in the disaster.
On the matter, a Manchester United spokesman said: "We welcome the apology."
The Merseyside club will play the Red Devils twice in September as they meet in the Premier League this weekend and go head-to-head at Old Trafford later on in the month after the two rivals were paired together in the Capital One Cup third round draw.
