He travelled around Europe at an early age, rambling in England, Germany, Switzerland and Spain.
Seán Cannon had known The Dubliners for years and, like Eamonn Campbell, joined them on stage on numerous occasions.
When The Dubliners announced their retirement in 2012 after finishing their 50th Anniversary Tour, Seán Cannon decided to keep on touring with former band members Patsy Watchorn and Eamonn Campbell and Banjo player Gerry O'Connor under the name of "The Dublin Legends".
He played gigs with Irish songwriter Pat Cooksey and more recently with his sons, James and Robert Cannon.
They call themselves "The Cannons" and perform traditional Irish folk music as well as songs by Shane MacGowan, Bob Dylan, Johnny Cash and Hank Williams.
