Irish music was bred into us from the day we are born. Looking back to our ancestors and our heritage, it was always in our culture. Even through the hardest of times Irish people always turned to music. They have a song for everything – for drinking, for depression, for famine. I remember a song growing up that was for milking the cows.
Agnew is a member of the Roman Catholic Church. She often says prayers just before going on stage to "Calm her nerves".[12]
