Bob Schieffer and Brad Paisley are buds…

Despite an early Sunday wake-up call, the “Face the Nation” anchor was out late at the Brad Paisley and Darius Rucker concert Saturday night with CBS Chief Justice correspondent Jan Crawford and his assistant Kaylee Hartung.

Sporting a jacket with his own band’s name “Honky Tonk Confidential” embroidered on the back and his signature cowboys boots, Schieffer even made it on to the tour bus to say hi to his old pal.

Schieffer and Paisley originally met on the stage of the Grand Old Opry in Nashville during the 2008 debate season. Paisley and his wife actress Kimberly Williams were then guests of CBS at the 2009 White House Correspondents Association Dinner.

But Bob’s party didn’t end there… Schieffer and his entourage even made a late-night appearance at Jim Courtovich‘s Gaucho party. We hear CBS expects “Face the Nation” ratings to jump up this week- everyone at the Gaucho party certainly tuned in to make sure Schieffer made it to the set after calling it a night at nearly 1am…
