Celtic Woman When founding member of
Celtic Woman Lisa Kelly went on maternity leave, Sharpe became a temporary member of the ensemble in 2008, saying that "I'm just in for this tour," and "It's a different style than I'm used to. But I've enjoyed learning the technique. My background is musical theatre, so this is something very different for me...But my philosophy is, you're always growing as a performer. There's always so much to learn." She admits that before she joined, she was not familiar with the group's music; "I'd never seen any of their shows...David (Downes, composer and music director of Celtic Woman) gave me a CD and some DVDs, and that was the first time I'd seen any of it." In 2009, Sharpe became a permanent member of Celtic Woman, in effect replacing
Órla Fallon. She has said that "The other members have been really encouraging," and "They have such a history together. I've never been in anything with such a high profile; usually you're much more anonymous." The group toured North America from February to May 2010 on their 'Songs from the Heart' tour. After the tour finished, Sharpe announced she would be leaving Celtic Woman to be with her family full-time. With the group she performed for
President Obama and also at
Radio City Music Hall. In early 2015 it was announced that she would rejoin Celtic Woman for two months (May and June) of their Tenth Anniversary tour. In 2018
Homecoming – Live from Ireland Tour, Alex Sharpe joined the group
Celtic Woman as a temporary fill-in for
Susan McFadden who was home for two weeks due to the death of her aunt. Later, McFadden was replaced by
Megan Walsh in the new album
Celtic Woman: Ancient Land Post-Celtic Woman On 11 July 2016 it was announced that Sharpe was forming a new group called
CaraNua with friend from Celtic Woman days Lynn Hilary. The direct translation of CaraNua is New Friend. It was chosen in part because it, not so commonly, sounds the same whether Irish or English letter sounds are used. The all Irish trio initially included
Lynn Hilary and Edel Chan Murphy, both former singers of Celtic Woman and Riverdance. This trio made the album Favorite Hymns with Jason Tonioli, and the singles A Million Dreams (a cover from the award-winning soundtrack of The Greatest Showman), and Remember Me (a cover of the Oscar winning song from the movie Coco). Murphy's departure prompted the arrival of Lisa Nolan. In 2017 Sharpe provided the vocal, in modern Irish Gaelic, for the traditional hymn Be Thou My Vision on Camille Nelson's, mainly instrumental, album "Lead Me Home." The album won the 2018 IMEA award for Christian/Gospel Album of the Year, and Be Thou My Vision was nominated for Christian/Gospel Song of the Year. In 2019 Sharpe again collaborated with Nelson on a cover of the Oscar winning Song into the West from Lord of the Rings: Return of the King. ==Personal life==
