So, the insanely talented bandleader on James Corden’s Late Late Show is a guy named Reggie Watts. Astute readers of Heathen should note that the first mention here of Watts or his output is actually in the long-ago era of 2002, when I hipped you all to Watts’ prior band Maktub; here’s a YouTube clip of one of their songs.
Watts came up again in as a solo performer in 2007 here; that video link is dead, but the clip is available at YouTube.
Somewhere along the line, Watts pivoted to comedy; you can see he’s there already in his 2012 TED talk, which I just saw (again) on a “best of 2010s” list, and so here we are.
