Gilmour will be allowing fans to download the Pink Floyd song Arnold Layne for the first time. The remixed song is being released in memory of Barrett, who died in July at the age of 60.
Gilmour, who joined the group shortly before Barrett left in 1968, has recorded two versions of Arnold Layne and an accoustic recording of Dark Glove from Barrett’s solo work.
The new version of Arnold Layne features David Bowie and Pink Floyd keyboardist Richard Wright.
The song will be available for downloading on November 25.
