What Lord Nelson would have made of his new neighbours is anyone's guess, but a winged harpist, a playwright and a mother singing nursery rhymes are among those Scots who have been chosen to occupy Trafalgar Square's fourth plinth.

They are all part of a 100-day arts project by Antony Gormley - best known for his Angel of the North landmark. More than 200 people north of the border have been selected to take part in Gormley's One and Other sculpture, which involves a different person being on the plinth for an hour each, 24 hours a day for 100 days between July 6 and October 14.

The first 615 participants, including 53 Scots who will take part in the project next month, were announced yesterday after being chosen randomly by computer from 13,000 applicants. Over the 100 days, a total of 2400 people will take to the plinth.

Among them is musician Cheyenne Brown, 25, from Glasgow. She is expected to appear on the plinth in 5ft-high wings, huge boots and bright hair, stopping passersby in their tracks to promote the Scottish harp.

"It will be a very striking visual image," said Cheyenne. "I really want to make a statement and take Scottish harp music in a new direction. I have a few ideas about what I am going to do."

Ms Brown, who will be performing on Saturday, July 18 at 9am, will be playing traditional and contemporary music as well as improvising.

Originally from Alaska, she came to Scotland on a scholarship in 2002 to study traditional music at the Royal Scottish Academy of Music and Drama in Glasgow.

She was first inspired to play Scottish music at festivals in the US, to where she has since returned as a tutor and is involved in the Scottish Harp and Cello Festival, now in its fourth year in the city.

The fourth plinth was originally created to accommodate an equestrian statue but because of insufficient funds nothing was ever commissioned and it remained unused until 1999.

Now its aim is to raise awareness of art to the public and generate cultural discussion. Works which have been displayed on the plinth include Marc Quinn's Alison Lapper Pregnant and Thomas Schutte's Model For A Hotel.

Jane Wilson, 36, from Largs in Ayrshire, will be singing nursery rhymes when she takes to the plinth.

Her hour slot begins at 7am on July 27 and her family will be able to watch her back home through a live link-up.

Mrs Wilson said: "I have always been interested in what will fill the fourth plinth in Trafalgar Square and when I saw this on a website I decided to apply. I never thought for one minute I would be chosen, but am delighted as it will be part of British history.

"I will be singing nursery rhymes and as a mum-of-three that is no problem for me. From Wheels on the Bus to the Grand Old Duke of York, my family will be able to watch me up there, and at the same time I will be raising money for my daughter Molly's nursery, Largs pre-school."

The Trafalgar Square surroundings may well be the inspiration for Glasgow-based playwright Tim Nunn when he appears on the plinth. With just a working title of Tank Man, inspired by a lone protester facing down a tank in Beijing's Tiananmen Square protest in 1989, the former human rights campaigner plans to write a short play.

Mr Nunn, who will be appearing on Saturday, July 11 at 4pm, said: "I suppose it is a performance in a way. All I need is a notebook and a pen and I will write the play on the plinth. I may also be inspired by my surroundings as I have got a great time slot."

The short play will be performed ahead of another of Tim's works, Funny, which will run at the Edinburgh Fringe in August.

He is also involved in Reeling & Writhing, a Glasgow theatre company he set up with Katherine Morley.

Participants for the plinth come from all over the UK, range in age from 16 to 83, and include a blacksmith, professor and rubbish collector.

Applications for the project will remain open until September 1 and places will be allocated in three further phases. Those wishing to take part can go to www.oneandother.co.uk.
