Paddy O'Brien will be our special guest this Saturday 3 pm on "Folk Music & Beyond." Paddy will demonstrate his mastery of the accordion and talk about his remarkable musical memory for traditional tunes. He has collected more than 4,000 compositions—jigs, reels, hornpipes, airs, and marches, including many rare and unusual tunes. Paddy will open the Crossroads Irish-American Festival in San Francisco this weekend.
