The organiser of a series of concerts supported by Longford County Council believes a longer time period is needed to implement new guidelines.
All indoor entertainment, cultural, community and sporting events are to be capped at 50 percent capacity from tomorrow, following latest Government guidance.
A concert taking place at the Backstage Theatre tomorrow night will be affected by the new measures.
Speaking to Shannonside Northern Sound Shane Crossan says people who bought tickets most recently will be contacted and asked to attend alternative events.
He says there is also financial challenges attached to the capacity limits.
