Patrick "Paddy" Casey is an Irish singer-songwriter from Dublin. From an early age he spent a great deal of his time learning his craft by busking on the streets of Dublin and Galway. Paddy was discovered by Sony A&R Scout Hugh Murray at the International Bar in Dublin, while performing at the legendary singer/songwriter night hosted by Dave Murphy. Paddy was signed by Sony, and was eventually taken in by U2's management company, Principle Management.
