Dublin. Terrific to write about, terrible to experience. This was the verdict of Patrick Kavanagh, poet, alcoholic and failure, born in 1904 and now brought back to life in Russell Kennedy’s enjoyable show at the Old Red Lion. Kavanagh’s assessment of Dublin would be better applied to himself. He cuts a shambolic, repellent figure in his knackered spectacles, squelching shoes and moths’ nest jumper, as he shuffles about the city’s pubs cadging drinks, lusting after female students and cursing the reputations of greater talents than his own.
