A brother and sister duo have just gone viral with their powerful rendition of the classic Dolly Parton song “Jolene.”

The video opens with Zach on the drums and Bekah on the guitar. She simply asks her brother “ready buddy?” and he responds by happily exclaiming “Ready!” Zach clearly could not wait to be a part of his sister’s music!

The video perfectly sums up the relationship that this brother and sister have with one another. Zach has Down syndrome, but Bekah is always there to support him every step of the way in life! In return for the love and encouragement that she gives him, Zach brings so much fun to Bekah’s life.

Seeing the two of them performing together side by side is a truly beautiful thing to witness. Zach is lucky to have a sister like Bekah, and she really is lucky to have a brother like him!

While Bekah brings a beautiful voice to the performance, Zach’s harmony brings a lot of love to the song. Video of their performance has quickly gone viral, being viewed over one million times!
