Pink Floyd heading for first number one in 20 years
Pink Floyd look set to achieve their first number one album in nearly 20 years with The Endless River, according to midweek figures from The Official Charts Company.
The album has sold more than 92,000 copies, putting it on course to become one of the fastest-selling albums of the year.
The band say it is likely to be their last studio album.
The Foo Fighters are currently in second place with Sonic Highways.
The US band's eighth studio album looks set to be their tenth UK top 40 hit.
The Endless River is a tribute to Pink Floyd's keyboard player Rick Wright, who died in 2008.
It is based on unreleased material from recording sessions for their 1994 number one album The Division Bell.
Wright, who was also a founding member of the band, appears on the record posthumously.
Pink Floyd guitarist and singer David Gilmour told the BBC 6 Music Wright was "underestimated by the public, by the media and by us at times I hate to say. I didn't necessarily always give him his proper due."
Bandmate, drummer Nick Mason added the album "is a great opportunity to recognise, remember and maybe give some credit rather late on."
Pink Floyd have previously achieved 27 top 40 albums, with five topping the album chart. Their last one was Pulse in 1995.
Making up the rest of the top five in the midweek album chart are Sam Smith's In The Lonely Hour at three, followed by Ed Sheeran's X, at four.
At five are Queen with Queen Forever, which includes three previously unreleased songs, including a collaboration with Michael Jackson entitled There Must Be More To Life Than This.
In the singles chart Cheryl Fernandez-Versini looks set to lose her record-breaking number one spot to Gareth Malone's All Star Choir.
On Sunday she became the first British female solo artist to have five number one singles in the UK.
Malone's All Star Choir have recorded the official Children In Need, a cover of Avicii's Wake Me Up.
Meanwhile Tom Odell's Real Love which features on the John Lewis Christmas advert has leapt 14 places to number seven.
