Pet Shop Boys unveil 'Leaving' music video - watch
The duo will release 'Leaving' on October 14 as the latest cut to be lifted from their recent album Elysium.
The single will also be available physically on CD and 12" vinyl from October 15 and will contain extra tracks and remixes.
New tracks include 'Hell' - which was originally planned to feature on Elysium - and 'In His Imagination'.
A limited-edition 7" of the single will also be available only from independent record stores across the UK as Pet Shop Boys are keen to promote physical releases on CD and vinyl, commenting: "We think every day should be Record Store Day."
Meanwhile, members Neil Tennant and Chris Lowe will sign copies of 'Leaving' at the Rough Trade East store in London from 7pm on October 17.
