Last night Joe Bonamassa had Paul Shaffer on as his guest, another wonderful interview in Nerdville - At 30:48 Joe asked Paul of all the hundreds and hundreds of musical guests, who stood out the most. Paul replied that James Brown's first appearance on Letterman was very special. I looked it up - holy moly!! Truly the hardest working man in show business and the Godfather of Soul! You could tell the Letterman band was just totally enjoying this one.. for the ages.
