Slack-key guitar virtuoso Makana is is scheduled to perform at the White House today at a holiday reception hosted by the first family, press agent Scott Foster said.

"He just called me and he doesn't know all the details yet," Foster said. "It was out of the blue."

Foster said the 800 invited guests include friends, diplomats and White House staff. He said other entertainers will be performing, but as of yesterday he didn't know who.

This is Makana's third visit to the East Coast and his second to Washington, D.C., in 2009. His April 3 concert in New York's Sage Theater garnered a rave review in The New York Times.

SAWYER LEAVING 'GOOD MORNING AMERICA'

ABC's Diane Sawyer says goodbye to "Good Morning America" this week after 2,881 shows — not that she's counting.

Sawyer announced on yesterday's show that her last day will be Friday. It will give her one week off before she switches to the evening, taking over as anchor of ABC's "World News" for the retiring Charles Gibson on Dec. 21.

The "Good Morning America" stint was probably some 2,700 shows more than she expected. With the show in serious ratings trouble a decade ago, Sawyer and Gibson agreed to a temporary stint as co-anchors. Things went so well they stayed on indefinitely, and Robin Roberts replaced Gibson when he went to "World News."

WEEZER CANCELS SHOWS AFTER BUS CRASH

Weezer has canceled its remaining December tour dates after a tour bus crash early Sunday left lead singer Rivers Cuomo with three cracked ribs.

Cuomo and band assistant Sarah Kim suffered minor injuries when the group's tour bus skidded on ice, struck a guide rail and slid into a ditch. The rest of the band, as well as Cuomo's wife and daughter, escaped injury.

Cuomo and Kim were hospitalized after the accident about 40 miles west of Albany. They were traveling to a show in Boston. A message on the band's Web site says Weezer is canceling the rest of its Raditude tour and will try to reschedule those dates.

BRITISH TV APOLOGIZES FOR RAT EPISODE

British broadcaster ITV has apologized after two contestants on a reality TV show skinned, cooked and ate a rat during filming.

Chef Gino D'Acampo and actor Stuart Manning have been charged with animal cruelty after preparing and eating rat risotto on the wilderness show "I'm a Celebrity ... Get Me Out of Here" last month. They were charged after complaints by animal welfare activists in Australia, where the show is filmed. The maximum penalty is three years in prison.

ITV said yesterday that producers had sought health and safety advice about eating the rat but had failed to check whether killing it was legal.
