Formed in Galway in 1966 by Joe Dolan from Galway (not the cabaret singer), better known as Galway Joe Dolan, Andy Irvine from London and Johnny Moynihan from Dublin. Irvine and Moynihan were traditional music enthusiasts who knew each other from the folk scene in Dublin and travels to Fleadh Ceoil around the country during 1963-65. Dolan had played guitar with second division showband the Swingtime Aces. In January 1965 Irvine and Dolan formed the short-lived ballad group The Liffeysiders with Dolan's friend Kevin O'Carroll. Moynihan wasn't impressed and they soon split anyway. This left it open for Irvine, Dolan and Moynihan to form Sweeney's Men. Des Kelly became their manager and got them a deal with Pye. Kelly also managed the Capitol Showband which is how various Sweeneys guested on three Capitol singles released during 1966.
