LAST DECEMBER ERIC CLAPTON, THE Odin of rock guitar gods, toured Japan with George Harrison. But it's only now that Clapton is letting his guitar gently weep as he delivers a sit-down acoustic show for MTV Unplugged (Wed., March 11, 10 P.M. ET). In addition to "The Circus Left Town," a song about his young son, Conor, who died tragically last year, Clapton plays a sweet, rangy set that takes in something old (a revamped "Layla"), something new (the never recorded "Lonely Stranger"), something borrowed (Bo Diddley's "Before You Accuse Me"), all of it blue.
One Irish Rover (Tues., March 17, 9 P.M. ET) is a horse of a different color: green. To honor St. Patrick's Day, A&E presents a peripatetic Van Morrison. Among other settings, the Irish singer engages in a duel with Bob Dylan on an Athens hilltop, a blues jam with John Lee Hooker on a dock by a Louisiana bayou and a Belfast performance of "Raglan Road," with Irish flavoring added by the Chieftains. It's a beautiful musical memento.
