One of his earliest highlights of his career was the honour of performing the tribute songs for the All Ireland finals of 1996 in which his native country took the hurling title .
He took American television audience by storm in 1999 as a member of the wildly-popular PBS super-group, The Irish Tenors which he continues to tour with twice a year. His international solo career includes high-profile celebrity engagements, television appearances, concert tours, and collaborations with the finest orchestras, including the Boston Pops, the Chicagoland Pops, Grand Rapids (MI) Pops, and the National Symphony Orchestra at the National Memorial Day Concert in the USA.
Mr. Kearns made his official U.S. Grand Opera debut as the tenor in the role of “Edgardo” in Gaetano Donizetti’s Lucia di Lammermoor with Opera Naples [Florida]. Since then, he has starred as: “Don José” in the Dun Laoghaire/ Rathdown Glasthule Opera Company’s production of Georges Bizet’s Carmen; the tenor with the Royal Dublin Society in The Lily of Killarney (part of "The Irish Ring" trilogy) which toured North America; the tenor role of “Don Ottavio,” in Mozart’s Don Giovanni at the Lismore Music Festival; and “Alfred” in a concert-staged performance of Johann Strauss’ operetta, Die Fledermaus by the Emerald City [Steamboat Springs, CO, USA] Opera. Upon moving to the U.S., Kearns returned to Opera Naples as the tenor in Charles Gounod’s Faust, a role he also performed with Opera Ireland (nominated for best production in the Irish Times Theater Awards). Other roles include “Fenton” in Giuseppe Verdi’s Falstaff (in Montepulciano, Italy) and “Nemorino” in Donizetti’s most performed opera, L’elisir d’amore, with Gulfshore Opera in Naples, FL in May of 2016 and most recently with Lismore Opera Festival Co Waterford Ireland in June 2017 .
