It’s Siren Saturday at the Rhythm Club, and Maureen O’Shea will be there to sing some Irish tunes. The owner loves them, but Coco worries that the crowd will be bored and leave. Besides, Miss. O’Shea is very high maintenance, and let’s face it: it’s the 1920’s, and Maureen just ain’t got that swing. Lightly interactive with the audience and easy to perform.
