This week on A Prairie Home Companion it's a mix of shows from the Town Hall in New York City back in April 2009. Wynton Marsalis and his Quintet perform "Powdermilk Bisquit," he appears as a subway busker in an episode of Guy Noir, and he joins Heather Masse as she sings Dave Frishberg's "Peel Me a Grape." Elvis Costello sings "Changing Partners" and "Down Among the Wine and Spirits," and appears as the great singing cowboy Roy Costello. Plus, Tom Rush sings "Drift Away," and the story of a mysterious white Panama hat that used to belong to Mr. Turnblad and its appearance at the Lake Wobegon High School prom.
