On Saturday 8 December, Scotland's four largest cities will cumulatively host 12,000 people and attempt to raise £6 million in the fight to eradicate homelessness. Edinburgh's event will take place in Princes Street Gardens, Aberdeen's in Duthie Park, Dundee's in Slessor Gardens and Glasgow's at Kelvingrove Bandstand.

Co-founder of Social Bite, Josh Littlejohn MBE, truly believes that this project can be the sea-change Scotland needs to stop homelessness: 'By coming together, we can accelerate the pace of change in Scotland and create the political mandate to truly end homelessness here. I fundamentally believe that the statistics of homelessness in Scotland are not insurmountable. By collaborating, and treating homelessness as a political priority, I believe that Scotland can be a country where everyone has a place to call home'.

This year the lineup includes an impressive array of artists helping participants get through the cold night. Amy MacDonald and KT Tunstall will play in each of the four cities, travelling between them by helicopter.

Edinburgh's lineup includes an acoustic set from Lulu and a bedtime story delivered by Trainspotting author Irvine Welsh. In Dundee, Kyle Falconer and Withered Hand have confirmed that they'll be there to keep the crowd awake and in Aberdeen, the job will be undertaken by Eddi Reader, Kris Drever and Adam Holmes & the Embers. Over at Glasgow's event, Frightened Rabbit will curate the event and perform with guest vocalists alongside Stina Tweeddale from Honeyblood and an act that they have specially selected. All four lineups also include local acts, still to be confirmed, that will play to the sleepers through the night.

The £4 million raised from the standalone Edinburgh event last year went towards the completion of the Social Bite village and the Housing First programme that both work to bring homeless people into mainstream tenancies across Scotland.

Scotland's Housing Minister, Kevin Stewart, commented: 'Public support for events like the Sleep Out demonstrates the appetite for change and the Scottish Government absolutely shares this commitment to ending homelessness. It's great to see the events being expanded throughout Scotland and I'd encourage everyone to get involved.'

To take part in Sleep in the Park, all you need to do is commit to raising £100. If you are a business you can sponsor the event by signing up a team of five, with a fundraising commitment of £3000.
