Background: Andrea Jane Corr MBE (born 17 May 1974) is an Irish musician, songwriter, and actress. Corr debuted in 1990 as the lead singer of the Celtic folk rock and pop rock group The Corrs along with her three elder siblings Caroline, Sharon, and Jim. Aside from singing lead vocals Corr plays the tin whistle, the ukulele, and the piano.
Context: In 1990, Corr and her siblings formed a quartet called The Corrs. Their career launched in 1991 when they auditioned for the film The Commitments in which Andrea gained a speaking role as Sharon Rabbitte. John Hughes noticed the quartet when they auditioned for the movie, and agreed to become their manager. The Corrs signed with Atlantic Records in 1995 and travelled to North America to record their debut album Forgiven, Not Forgotten. The album featured six instrumental selections among its Celtic-influenced tracks. When released, it was successful in Ireland, Australia, Japan, and Spain. The album reached platinum status in the United Kingdom and Australia, and quadruple platinum in Ireland, which made it one of the most popular debuts by an Irish group.  Following on from the success of their debut album, they released Talk on Corners and In Blue in 1997 and 2000 respectively. Originally Talk on Corners met with lukewarm success, until a remix version was released, when it topped the charts in many countries, and reached platinum status in the United Kingdom and Australia. In Blue moved towards mainstream pop, placing heavy emphasis on electronic synthesisers. It was successful, and was No. 1 in its first sales week in the UK, Ireland, Australia, Germany, Switzerland, and Austria and debuted at No. 2 in France and Norway. It climbed to the top position during its second week in Sweden and Spain.  During the production of In Blue, their mother, Jean, died while waiting for a lung transplant in the Freeman Hospital in Newcastle, Britain. She was laid to rest at St. Patrick's cemetery in Dundalk. Bono, Larry Mullen, Brian Kennedy and Paul Brady were among the attendees. "No More Cry", written by Andrea and Caroline Corr for the album, was dedicated to their father hoping to help with his grief.  In 2003, Andrea recorded "Time Enough For Tears", a song written by Bono and Gavin Friday for the film In America. This track was featured on The Corrs' 2004 album Borrowed Heaven. Borrowed Heaven was dedicated to their late mother, Jean, and their father, Gerry. The band also dedicated their 2005 tribute album Home to their deceased mother. The band covered many traditional Irish songs taken from their mother's songbook to commemorate their 15 years as a band.  In an interview with Chris Evans in June 2015, Andrea confirmed that The Corrs were working on a new album and would play the BBC Radio 2 'Live in Hyde Park' festival. Their sixth studio album, White Light, was released on 27 November 2015, and was accompanied by a world tour.
