Two unlikely actors — Alan Jackson and former British Prime Minister Tony Blair — are featured in the latest White House online video featuring the first family’s Scottish terriers, Barney and Miss Beazley. President Bush, wife Laura and daughters Jenna and Barbara also have roles in the seven-minute video titled Barney Cam VI: Holiday in the National Parks. In it, the canines dream of becoming junior park rangers while they wander around the White House. In one of the dream sequences, Jackson makes a cameo appearance and says, “Junior park ranger? OK, Barney, now you’ve gone country.” In a subsequent dream sequence, Blair congratulates the two dogs after they’re named junior park rangers. “Well done,” he says. “As someone born in Edinburgh, Scotland, it’s always good to see the Scots doing well.” View the video.
