A pair of sisters are overjoyed as a song they recorded for their nana and papa has reached millions more.

Two Fort Francis sisters making a video for their grandparents are being heard far and loud this Easter.

"Sisters Cassandra (10) & Callahan (19) wanted to record this beautiful & meaningful version of Hallelujah especially for Nana & Papa since it’s their favourite," their mother Nikki Armstrong-Wiedenhoeft writes on Facebook. 

The lyrics to the Easter version of Canadian Leonard Cohen's Hallelujah were written by Kelley Mooney.

"My Mom was able to watch it today and it really touched her heart. We pray that healing and comfort will be with her soon. My Dad was also emotional when he listened to this tonight. An important song at the perfect time."

The ten-year-old writes on YouTube the sisters have almost cried at the kind comments.

"We are so happy that we touched your hearts because that is what we wanted. We wish we could hug all of you because you are all VERY special and kind. The world is really sad right now and we wanted to give you hope. Everything is going to be okay we just need to love each other more."

Cassandra has recently made local news for her entertainment projects, including videos where she reads stories.

Callahan says "our hearts are overflowing with joy hearing from people all over the world." She is a pre-med and music student. At Christmas, she received attention for covering 'Ave Maria' and 'O Holy Night' and earlier, a cover dedicated to her late brother did the same.

The sisters are working on a version of 'Amazing Grace.'
