I'm not entirely sure why more late night talk shows don't book interesting events like Jimmy Fallon has with his Bruce Springsteen event this week. Springsteen performed songs from his forthcoming album on Monday and will return on Friday, and mid-week, musicians cover Springsteen songs. Tuesday, Kenny Chesney did a nice job with "I'm On Fire" and last night John Legend and the Roots delivered a jazzy take on "Dancing in the Dark".
Once upon a time, there were only so many places you could live music performances, so when a group appeared on TV, it was sort of an event. I remember begging my parents to let me stay up to watch R.E.M. on Letterman's NBC show, but now I can jump on YouTube or elsewhere and see nearly any band anytime I want. I'd be far more likely to tune into a talk show (something I rarely do in the DVR era) if something unique and unexpected was likely to occur in the musical guest slot of the program. What John Legend and the Roots came up with certainly counts.
