The special limited edition release sees Sunshine On Leith pressed for the first time on 7” clear green vinyl.
Money raised by sales of the single will help Edinburgh and Lothians Health Foundation continue to provide additional support for NHS Lothian staff during one of the largest global health crises in generations.
It will also enable them to put in place a programme of longer-term, sustainable wellbeing support that will address the lasting effects of the Covid-19 pandemic, both in the recovery phase and in the longer term.
In aid of this, The Proclaimers are also releasing 100 limited edition signed copies, available to pre-order now exclusively through Hibernian Direct.
"We’re very happy to be supporting NHS Lothian during this challenging time for our people and health service,” said Leith-born twins Craig and Charlie Reid in a joint statement.
“The NHS is very much loved by both of us and we have much reason to be grateful to it.”
Hibs captain David Gray said: “Sunshine On Leith is a phenomenal club anthem and I’ll never forget it ringing out around the east stand of Hampden during the celebrations of the Scottish Cup Final in 2016 – it was a proper hairs on the back of your neck moment.
“It’s such a powerful track, and whenever I hear it I always get a buzz thinking back to that day.
“This limited edition version of the track is a fantastic gesture from The Proclaimers in support of The NHS and Edinburgh and Lothians Health Foundation – and it’s great to see them partner with the club for such a great cause.
“Our NHS heroes have been brilliant during this pandemic and even before then and we wear the ‘Thank You NHS’ message on our shirts with pride.
“I’m sure our fans will snap up this limited edition version and raise plenty money for the charity. I’ll be after one as well.”
Originally released in 1988, Sunshine on Leith is the second single and title-track from their album of the same name.
