As Dave mentioned earlier the Grehans appeared at Folk Union One, Hull, several times. We are collecting together recordings from the club around that time and it's very likely we will have some of the Grehans. At the moment we are raising funds to have the recordings digitised to go into the Hull Folk Archive. When that happens if there are any Grehan recordings it will be easy to run off copies for people here. I'll keep this in mind and come back to this thread when I have further news.
