Tickets for a free Van Morrison concert will be drawn from a lottery.
Fans are being invited to enter the online competition for the gig in his native Belfast to celebrate him being conferred the freedom of the city.
Two thousand tickets for the Waterfront Hall show on November 15 are up for grabs.
Council chiefs said residents from across the city can enter the draw from Tuesday online at www.belfastcity.gov.uk and www.waterfront.co.uk or in person at the Waterfront Hall booking office.
Fans can enter the competition up until 5pm on Wednesday October 30.
A computerised draw will ensure tickets go to a spread of people from different parts of the city, Belfast City Council said.
Winners will receive two tickets each for either a standing or seated area.
