I went to see the Bumpstead Boys and Beryl recently, a group of entertainers in Suffolk, and one of them sang Messing about with your Liver, a complete song about the demon drink, and drunks, and pub singers. Today is the first time i've read this thread so it jogged my memory. As for the words, sorry, no chance after only hearing them once. They seemed to be quite well known so maybe someone else will know who the singer is.
