Marwenna Diame is a professional Scottish songwriter.

Nathan Osmond is from an American musical icon family.

They've recently collaborated with vocalist Amy Van Wagenen and producer Dave Allott to mark the coming together of the Scotland and Ireland missions with a charity single, "Till The Work is Done." The profits go to The Church of Jesus Christ of Latter-day Saint's missionary fund.

"We were commissioned by Mission President Gary Griffiths to write a song as an anthem for the missionaries to sing," Jones told the Mormon Times. President Griffiths visited Diame last year during a trip to the Sotrnoway Isle of Lewis branch in Scotland.

Diame had received a blessing earlier telling her she needed to write songs to uplift the Lord's church.

"I usually write pop songs for world artists and didn't know how that (writing songs for the LDS Church) was going to come about," she said. "I prayed for a few months. Then one day I got a strong impression to telephone President Griffiths."

President Griffiths told her he knew why she was calling and that the Lord had told him what she was to do.

He explained that the Scottish and Irish missions were being combined and that he wanted a song for the missionaries to sing an anthem/hymn-like song that they could sing at conferences, a song that would make them feel a part of one mission.

"I didn't know who I could work with on it," Diame said. "He said, 'Don't worry, sister, the Lord will show you.'"

In the United Kingdom, there are not a lot of LDS people in the music industry. Diame knew she needed someone who was a member of the Mormon church.

"With all the faith I could muster I prayed that if I went onto the computer that the first recording studio that would come up would be owned by an active Mormon. So I typed in 'recording studios uk' and called the first one that I saw," she said.

It was a studio owned by Dave Allott, a Mormon and someone Diame had known for years. He had moved from Wales to England. Jones explained everything and he agreed to produce the backing track at his studio.

Next needed was a singer. Diame had been a vocal coach for the Osmonds when they were children so she called Nathan Osmond.

"We wrote the song together over the phone," Diame said.

Osmond said he "was thrilled to no end" to be asked to join the project.

"I've had the privilege of traveling to both of those countries and even have a lot of ancestory from each," he said. "I believe that music has the ability to unite people and I feel like this song is going to do just that. Missionary work is the greatest work in the world and I am honored to be part of such an historic project."

He said it was challenging to try and write a song "across the pond."

"Thanks to technology, Marwenna and I were able to bounce ideas back and forth until we came up with the right melody and lyrics. It has a nice Scottish-Celtic feel to it. We even added bagpipes to give it that finishing touch. I can't wait to hear all the Irish-Scottish missionaries singing this anthem," he said.

Diame called Amy Van Wagenen next.

Van Wagenen said making the CD was truly a labor of love. "Hopefully, this work will strengthen the missionaries in the Scottish-Ireland mission," she said.

The next step was finding a good bagpiper.

"I just prayed that Dave would know one and he said, 'Guess what? There's a guy who lives near me who plays the bagpipes!'"

Van Wagenen said making the CD was truly a labor of love. "Hopefully, this work will strengthen the missionaries in the Scottish-Ireland mission," she said.

The next step was finding a good bagpiper.

After the backing track was finished it was sent to Osmond who recorded his vocals at a studio in Utah. Van Wagenen recorded her vocals in another Utah studio.

Diame recorded on the island with Keith Morrison who is not a member but agreed to record her vocals at his studio and sing on it because he felt a "great spirit about it."

Finding an affordable printer was also a challenge so Diame used the power of prayer again.

"I asked the Lord to help me find a printer for as little as possible and gave him an amount in my head. I went online and straight away one jumped out at me. The printer's girlfriend is LDS, and he agreed to print the CDs and the cover for an amazing price," Diame said.

"The only problem was I hadn't designed the cover yet. I asked the Lord what kind of cover he wanted, and an image of an old Croft and two bikes came into my head."

Diame called a friend, Jaq Drygate, who does professional CD covers for bands. He put it together.

The last hurdle involved getting the CDs out there so people could hear them.

"I spoke with Rebecca Fag whose father owns the LDS bookstores in the U.K., and she agreed to sell them for us. President Griffiths paid for them."

The CD single is available at LDS bookstores in the United Kingdom and at Positive Music Downloads.
