ALTERNATIVE folk duo The Portraits, who played at 2013's Glastonbury Festival, perform at St Petroc's Church, Padstow, on Saturday, May 3.
They are appealing for local voices to sing on the recording of their new single The Rest Of Time, which they hope will reach the Top 40.
The track, written about the power we each have to save a life, will accompany an urgent call for people to sign up to the Bone Marrow register at a time when many potential recipients still die before finding a donor match.
The duo will perform the new song at their Padstow concert, where the audience themselves will record one of several layers of voices that will be used on the final version of the single, planned for release in the summer.
For pianist and songwriter Jeremy Millington, the subject of the song and the cause are close to his heart following the death from leukaemia of his father Graham, who lived in Polzeath, a decade ago.
"My dad could have had more time," Jeremy said, "if the doctors had found a bone marrow match for him, which they tragically couldn't. I have always wanted to do something to raise awareness of the need for people to become donors to prevent others suffering the same loss that my family and I did."
Jeremy added: "Success as an independent musician is a game of numbers and of being realistic about what you can achieve. We are repeating our Padstow recording plan across the country over the next few months, ending up with a huge collage of voices. With so many involved, credited, and having an interest in its success, we're confident our song can land a place in the singles chart. The publicity generated has the potential to save lives and show that regular people can achieve something incredible."
