Hadrian's Wall of Sound round-up
Well, BBC Music Day in the North East has been amazing so far, full of colour and atmosphere as the musical relay spans the 73-mile length of Hadrian's Wall.
The baton is now on its way up to Cawfield Crags in the hands of BBC Newcastle sports presenter Simon Pryde. He will hand it to opera singer Graeme Danby.
There's quite a crowd at Cawfield. The sun has come out and it's beautiful, with the water and crag in the background.
Some words from the boss now. BBC Director-General Tony Hall writes: "I want to acknowledge the brilliant work that's gone into BBC Music Day, our first ever celebration of the part music plays in our lives and the BBC's role as enabler and entertainer.
"This afternoon, I'll be talking with Steve Wright on Radio 2 about what's happening, including a 70-mile musical extravaganza the length of Hadrian's Wall, Radio 6 Music live on the Liverpool waterfront and a big finale from Glasgow's City Halls.
BBCCopyright: BBC
"My thanks to everyone who's got behind the ambition. We're getting even better at delivering Britain's big moments - those huge annual events the BBC is rightly famed for."
Hundreds of local musicians are travelling its 73-mile (117km) length using various modes of transport and passing a baton from performer to performer.

Mid-morning radio presenter Anna Foster, who is with the BBC Music Day Hadrian's Wall of Sound relay for today's programme, says: "We've got all sorts of music, it's such an exciting thing to be part of - even if I am standing in a cow pat!"

It's not just Hadrian's Wall that is playing host to BBC Music Day.
In Cardiff, there will be a world record attempt as well as live performances from the BBC National Orchestra of Wales and a homecoming show from Welsh band the Manic Street Preachers.
As part of celebrations marking 150 years since the first Welsh settlers left for Patagonia, Shan Cothi in Wales and Andres Evans, 7,000 miles away, will attempt to break the world record for the greatest distance between singers of a duet.
As the Hadrian's Wall of Sound relay travels from Gilsland to Walltown Cragg, Frank Lee will play the melodeon with Cornelia Lee-Schrijver on the Northumbrian smallpipes. The melodeon, for the uninitiated, is a type of button accordion.
And here is Mr Colin Briggs in all of his finery. Quite the chauffeur, we think you'll agree.

Helen Amess's 'Eureka' moment came as she took in the spectacular views from the famous heritage site, and imagined community musicians of all shapes and sizes playing along its length, throughout one day.
The BBC Outreach coordinator for the North East tentatively raised the plan with executive producer Katy Jones, then leading the Music Day extravaganza.
"She thought it was awesome, got right behind it and was so supportive as the project developed. It needed her buy-in to really take off," Helen says.

Where can I join in?
With almost 600 musicians taking part in the relay, Hadrian's Wall of Sound will offer a mix of music throughout the day - from opera to indie, hip-hop to classical, pop to big-band.
Popular artists include opera singers Anna Flannigan and local-born favourite Graeme Danby, folk singer Maddy Prior and BBC Introducing's mylittlebrother.
Although this is not a ticketed event, there are several points along the route where audiences are welcome. Some highlights are listed here.
How Hadrian's Wall of Sound came about
Six months ago, a winter walking holiday along Hadrian's Wall inspired an idea so ambitious, it's now a centrepiece of the first-ever BBC Music Day.
Helen Amess's 'Eureka' moment came as she took in the spectacular views from the famous heritage site, and imagined community musicians of all shapes and sizes playing along its length, throughout one day.
The BBC Outreach coordinator for the North East tentatively raised the plan with executive producer Katy Jones, then leading the Music Day extravaganza.
"She thought it was awesome, got right behind it and was so supportive as the project developed. It needed her buy-in to really take off," Helen says.
Good morning and welcome

Good morning and welcome to something a bit different. As part of BBC Music Day, we're running an event called Hadrian's Wall of Sound - an ambitious, visually spectacular musical relay spanning 73 miles along the length of the iconic wall.
It begins at 06:00 at Bowness-on-Solway marshes in Cumbria, then travels through Northumberland and Newcastle before concluding in Wallsend.
Some 600 musicians from diverse communities along the wall will journey by bicycle, horse, open top vintage bus, motorbike and even unicycle, passing a baton from performer to performer.
The breathtaking scenery will be complemented by a mix of sounds showcasing string quartets, bluegrass bands, hip-hop artists and many, many more performers along the route. We'll have full live coverage here, and we hope you enjoy it.
