In an interview on the BBC website today, David Gilmour talks about the assistance he had from The Liberty Choir on his new single, the title track of the upcoming album Rattle That Lock.

The Choir includes former inmates from Wandsworth Prison where his son Charlie served time, and is a rehabilitation project that also includes local singers. Gilmour told the BBC that the choir gives prisoners "real hope and optimism. Charlie's experience was something that has impacted on us and has made us more aware of the prison system and what could and should be done to improve it. We're just helping out by being part of this initiative, which will hopefully spread."

Gilmour and wife Polly Samson have also donated money to allow The Liberty Choir to expand to other jails. "It's wonderful, seeing all these guys singing in the prison along with people from the South London Choir. They are close to the end of their sentences, and they then have a place outside prison where they feel part of the community, and that's very good for them, to feel valued."
