Further to the above - the album by the Dubliners is called Further Along and is post Ronnie Drew. The songs are called Back in Durham Gaol and If ever you go to Dublin - or so I am told by the friend who has the cd. They also perform The Crack Was Ninety In The Isle Of Man. Another song missing from my collection.
As many of the people who access this site appear to reside in the U.S. I'd be interested if they have ever come across an Anglo/Irish band called Kelly's Heroes. In my opinion definately one of the best groups around at the moment.
