PINK Floyd guitarist David Gilmour has revealed that his new single features former inmates from the prison where his son served time.

Gilmour, who has had homes in Hove and Wisborough Green, recorded Rattle That Lock with The Liberty Choir, a rehabilitation project that includes former Wandsworth Prison inmates and local singers.

His son Charlie was in Wandsworth in south London in 2011 after being arrested at a tuition fees protest.

He spent four months in jail after being convicted of violent disorder for his part in the 2010 protest, where he swung from a flag on the Cenotaph and threw a bin at a royal convoy.

David Gilmour said: "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."

Charlie Gilmour ended up serving four months of his 16-month sentence.

David Gilmour's single Rattle That Lock is out now and his solo album of the same name is out on 18 September.
