CARA Dillon and Sam Lakeman is not the only Lakeman musical link-up.

Sam's brother Sean is on tour with folk singer Kathryn Roberts, playing Pocklington Arts Centre tonight at 8pm, promoting their new album.

The husband-and-wife duo had been absent from the music scene for almost a decade before their 2012 return with Hidden People; Sean busy touring the world with a third Lakeman brother, Seth, while Kathryn remained in Devon, bringing up the couple's twin daughters. (As it happens, Sam and Cara have twin sons.)

After cementing their return by winning the Best Duo award in the 2013 BBC Radio 2 Folk Awards, Kathryn and Sean have now released their boldest musical statement to date, Tomorrow Will Follow Today.

Recorded in producer Sean's home studio, it combines eight originals with the incest, betrayal and murder ballad Child Owlet and the trad-inspired The Banishing Book.The album's conversation piece is the title track, which questions whether the holders of political power rely on the turning of the days, months and years to soften the blows of their ambition.

"The trigger for that song was a Terry Pratchett quote from Feet Of Clay, where he wrote: 'People believe they want justice and wise government but, in fact, what they really want is an assurance that tomorrow will be very much like today'," says Kathryn.

"Then we looked at songs from 1820 to 1900 gathered by the late Roy Palmer, where people were queueing up for food, and we thought 'that's still the case today', so we wrote this protest song. The tradition of folk protest-singing has died away a little, but as you get older, you grow more confident, hitting the point where you're not scared to express your opinion, and it just felt the right time to express those feelings, as we're parents and we worry for our children's future."

In another new composition, A Song To Live By, recorded on her trusty upright piano in their Dartmoor home, Kathryn offers heartfelt advice to her twin daughters, now aged seven and a half. "One day Lily had come home from school upset because she hadn't got to hand out the pencils that day, so we had a chat about how sometimes you have to put on a happy face," she says.

"I then wrote the song, initially for the girls, but Sean said 'there's something in this that will connect with other couples', and I've had so many requests for the lyrics that I've now had a greetings card made with them on!"
