Get Up, There Was A Time & Sometimes by James Brown (Letterman, 1982)

One of the most iconic late night performances ever. James Brown, with maybe the best backing band in late night, absolutely crushes his biggest hit before coming back for more after the commercial break. Electric. But wait there's more. After a few announcements from Letterman, Brown hits us with his THIRD song before the show fades out. Have you ever seen a studio audience so enthralled with a musical guest??
