John Byrne is an Irish saxophonist, composer and arranger whose musical versatility brings depth, warmth and style to every performance. In 2021 he won a nationwide competition to write the new signature music for RTÉ’s RTÉ Today show — a significant achievement that underlines his strength as a composer and creative artist.
Beyond his composing work, John regularly performs with top-tier artists. He’s known to play often with Nathan Carter — adding saxophone flair and musical richness to Nathan’s live shows.
As part of The Cosmonauts, John brings that same professional experience and musical sensitivity — blending smooth sax lines, emotive melodies or energetic horn-driven hooks depending on the mood. Whether it’s a romantic first dance, a heartfelt ballad, or a lively dance-floor anthem, his playing elevates the band’s sound with sophistication.
