Here’s a sit-in from Friday we don’t want to let pass. Lucinda Williams performed in Ft. Lauderdale at the Parker Playhouse. Then, following a strong performance (guitarist Blake Mills continues to draw raves, such as this one from Bob Lefsetz last month), the band brought out a surprise guest for the encore. Allman Brothers Band drummer Butch Trucks took the stage as Williams sang her take on the ABB classic “It’s Not My Cross To Bear.” Trucks will likely perform that tune once again next month when the Brothers return to the stage, while Williams is in Roanoke, VA at the Jefferson Center this evening.
