Gorman has revealed he won’t be playing Glasgow and Oxford on his 2014 tour because venues there charge up to £9 per ticket in additional charges.
Millican and Manford have already complained about the “whopping” fees charged by the Ambassadors Theatre Group, which sells tickets through its subsidiary ATG tickets.
TG has recently confirmed that it has been sold to private equity firm Providence Equity.
The cost of the deal has not been confirmed, but ATG is understood to have been valued at between £250 million and £350 million.
This would make the deal the largest ever brokered for a UK theatre company, according to The Stage.
