Dunfermline mum Nicola Urquhart has shared a video of her missing RAF son singing along to the musical Wicked.
The footage shows Corrie McKeague happy and laughing just a month before his disappearance.
His mum wrote on the 'Find Corrie' social media page: "This is hard to share but on the eve of new year, I would like you all to see the beautiful soul that we desperately miss.
"It makes me smile every time I watch this and I hope it makes you smile too."
Corrie vanished over three months ago during a night out in Bury St Edmunds on September 24.
He was last seen on CCTV at 3.25am walking alone after being separated from his friends.
Corrie's family have been organising searches and more than £50,000 has been donated to fund a private investigator.
Last week Tom Hardy also joined the appeal to find Corrie, releasing a video on Facebook asking for anyone with information to come forward.
