In this evocative and sharply tailored piece, David Heffernan takes us back to the dancefloors of 1970s Ireland — a world of mohair suits, platform shoes, and Dubonnet-fuelled dreams. From the revolutionary roots of disco in marginalised communities in New York to its shimmering takeover of Dublin’s club scene, Heffernan traces the music's global rise and local resonance. Part memoir, part cultural history, YES, DISCO unearths the glamour and grit of venues like Lord John and Sloopy’s, the fading charm of O’Connell Street, and the new urban identities being forged beneath spinning mirror balls. With nods to everyone from Donna Summer to U2, and stories of love, change, and weekend DJ sets in basement clubs, this is a vibrant portrait of a pivotal moment in Irish nightlife. For anyone who ever danced, or wanted to, this is a joyful, personal, and richly textured celebration of disco's pulse — and its enduring invitation to simply let go.
