Musical double act Foster and Allen last night vowed to appeal after admitting they “most certainly don't have the money” to clear €3m each in unpaid taxes.
The duo saw their challenges against demands by Irish revenue officials dismissed.
Tony Allen (60) said: “I have no idea where we are going to get that kind of money from.
“We believe that we wouldn't actually owe all that much money, most of it is made up of fines and interest.”
Mr Justice John Hedigan yesterday said the duo had brought “great joy” to many over the years, but the court had to rule against them.
Afterwards, Mr Allen promised to remain positive and continue his musical career with Mick Foster as they sought to appeal the Dublin High Court decision.
“It's not as if we have never been paying tax. We have paid tax every year since we started. This is just to do with royalties and record sales. It got out of hand a few years ago with an accountant we had who wasn't working the way we thought he was,” he said.
