Frightened Rabbit and Lulu are to perform at a charity sleep-out which is taking place across four cities.

Frightened Rabbit, whose lead singer Scott Hutchison died in May, said they want to "honour Scott in the best way we know" by playing at the Glasgow event.

Eddi Reader and Kyle Falconer have also been added to the line-up.

Social Bite aims to raise £6m from Sleep in the Park 2018 to continue its fight to eradicate homelessness.

It hopes 12,000 people will take part in Glasgow, Edinburgh, Aberdeen and Dundee on Saturday December 8 in what has been described as "the world's biggest simultaneous multi-city sleep-out".

Josh Littlejohn, co-founder of Social Bite, said: "To try and tackle homelessness head-on we've got to think big and Sleep in the Park 2018 is Social Bite's biggest ever campaign.

"Sleep in the Park will bring thousands of people together to raise funds so homeless people around Scotland are housed and given the support they need to get back on their feet.

"By joining the movement, participants can take part in an incredible night, enjoy some of Scotland's best bands and know that they're doing something that will really make a difference.

"I would like to thank all of the amazing music acts who are supporting the event, in particular Grant Hutchison and the other members of Frightened Rabbit, whose performance will be incredibly special and poignant."

Last December around 8000 people braved freezing temperatures to take part in the event in Edinburgh, raising £4m for the cause.

Frightened Rabbit played at Sleep in the Park in 2017 and this year will curate the Glasgow sleep-out in a show billed as Songs of Frightened Rabbit.

They will be joined on stage at the Kelvingrove Bandstand by vocalist James Graham, with more performers to be announced in the coming weeks.

Grant Hutchison said: "It's an honour to play for such a special event again and we felt it would be the perfect time for us to play together again and share this special night with some of our favourite artists.

"We had agreed to play Sleep In The Park before Scott passed and we felt that since it was something for such a great cause that we should stick to our decision and honour Scott in the best way we know - to play the songs he wrote and continue spreading his message of kindness whilst supporting Social Bite and the amazing work they do."

Lulu will headline the event in Edinburgh's West Princes Street Gardens and will be joined on the bill by Siobhan Wilson.

Eddi Reader will headline Sleep in the Park in Aberdeen's Duthie Park, while Kyle Falconer will top the bill in Dundee's Slessor Gardens.

Amy Macdonald and KT Tunstall will play all four cities, travelling by helicopter between the locations.
