The American will be taking a liberal stroll through a back catalogue which spans four decades and includes such gems as 'Help Me Make It Through The Night', 'For The Good Times' and – swoon – 'Me And Booby McGee'.
Tickets go on sale on Saturday March 27 priced € 39.50 and € 44.50.
As revealed on hotpress.com earlier in the month, the other SummerFest headliners are Bryan Adams (25) and The Corrs (26).
