A recording of the US leader singing 'Amazing Grace' at the funeral of a victim of the Charleston shooting earlier this year has been sampled by the band due to its "historical significance".

Obama touched hearts when he sang a solo of the Christian hymn at during his eulogy at the remembrance service of Clementa Pinckney - the South Carolina state senator and pastor who was gunned down in the tragedy when 21-year-old Dylann Roof entered the Emanuel African Methodist Episcopal Church during a Bible study and killed nine people on June 17.

Coldplay frontman Chris Martin said: "We have a tiny clip of the president singing 'Amazing Grace' at that church. Because of the historical significance of what he did and also that that song being about, 'I'm lost but now I'm found.' "

According to The Sun newspaper, Obama only agreed to let the British rockers use his voice on their LP because he "loves" the group.

A source close to the band revealed: "Barack Obama wouldn't let just anyone feature his vocals on the record, especially considering what a deeply emotional moment it was for him.

"But he clearly loves Coldplay and is happy to be a part of their music history. The band were obviously thrilled."

Coldplay's seventh studio album 'A Head Full of Dreams' will be released on December 4.
