The folks over at NBC sure know how to jam. At MSNBC’s 15th anniversary barbecue celebration on Thursday, NBC News President Steve Capus and Washington Bureau Chief Antoine Sanfuentes jumped on stage and took over for the band to close the lunchtime party with one of their favorite tunes. Capus whaled on bass while Sanfuentes rocked out on drums as the duo played their rendition of “Hang on Sloopy” for colleagues. We hear that both gentlemen are great entertainers.
