One Glasgow busker was in for a treat this weekend as he performed a duet with a difference.
Ben Monteith couldn't believe it when chart-topper Sandé asked to sing alongside him in Glasgow city centre.
Scottish superstar Emeli performed with Ben on Argyle Street on Saturday afternoon.
Droves of busy shoppers stopped in their tracks to watch Ben strum his guitar as Next To Me singer Emeli belted out some ballads.
Emeli was out in Glasgow searching for the county's best new musical talent as part of a new BBC Scotland series, Emeli Sande's Street Symphony.
Five outstanding street performers will join Emeli at a unique concert with the BBC Scottish Symphony Orchestra next month.
The search spread to Aberdeen, Perth and Edinburgh as well as Glasgow.
Emeli said: “I think this series is going to really celebrate the beauty and diversity of music, in all its forms, from a singer on the street to a classically-trained instrumentalist.
"I’ve only just started my search and I’m already blown away by the level of talent that’s out there.
“Music can bring great hope and it can encourage confidence, but above all the most important thing I’m looking for is authenticity – it’s got to be real."
The five acts chosen by Emeli will be honed to perfection and coached by the world-class orchestral conductor and composer John Logan before they join her for the performance with the BBC Scottish Symphony Orchestra at the City Halls in Glasgow.
Their stories will be told, along with the story of Emeli’s early years growing up in Alford, Aberdeenshire, as part of four 60-minute programmes to be shown on later this year.
Emeli's new single Extraordinary Being is out now.
