At my one man band shows, I perform a wide variety of styles including pop, rock n' roll, indie, country, Irish ballads and upbeat Irish songs. A good mix but also playing to the crowd. My goal is always to get everyone off their chairs singing and dancing.
I'm also the baritone vocalist of The Three Tenors Ireland. https://threetenorsireland.com/ We perform nationwide each year in venues such as the Mill Theatre, National Concert Hall, Cork Opera House etc. as well as many Churches and Cathedrals around the country.
I don't use backing tracks. I perform vocals and guitar live through a professional PA system and provide professional lighting. Some of the best nights have been when guests join me to sing a song of their choice, while I accompany them on guitar. It's great fun. (I always keep a spare microphone and stand ready!)
