Coming up on A Prairie Home Companion, an all-things-Irish compilation in advance of St. Patrick's Day on the 17th. Martin Sheen plays James Joyce in an episode of The Lives of the Cowboys, the late Frank Harte sings a tune from Finnegans Wake, and Pat Donohue has the Irish Blues. Plus, Sean O'Driscoll, Cathal McConnell and The Boys of the Lough, and Solas. In Lake Wobegon, Ronnie Detmer's uncle travels to Dublin to collect an inheritance. Grab your hankie for a "Danny Boy" sing-along and say a prayer for your sainted mother, this week.
