>Bravo's arts series The South Bank Show offers a special, Shamrock and Roll (Thurs., March 14, 8 P.M. ET). Fitting contemporary Irish music to Ireland's cultural heritage, it features interviews with and performances by Van Morrison, Sinéad O'Connor, U2 and others. Elsewhere, Robert Cray and Buddy Guy, bluesmen of disparate vintage (ages 37 and 54), each turn in sweaty sets on an excellent Austin City Limits (PBS, check local listings), which also contains a fiery filmed remembrance of guitarist Stevie Ray Vaughan. On Sunday (March 17, 9 P.M. ET) the Disney Channel presents Billy Joel in Concert at Yankee Stadium, a special that is lively both visually and aurally.
