Last night (5/21/15) was David Letterman's last show. Over the years Dave's show (first at NBC, then at CBS) has occasionally featured blues, and blues rock acts - and Dave appeared to genuinely appreciate this style of music. Thankfully these performances can usually be found on YouTube, so I spent about an hour tracking down as many as I could. This playlist contains 32 videos, spanning 30+ years, and features Stevie Ray Vaughan, Robert Cray, Jimmy Vaughan, Brian Setzer, Albert Collins, Gary Clark Jr., John Mayer, Johnny Lang, and others.
