Is it just me, or can the fact that NBC is using Sam & Dave’s “Hold On, I’m Coming” to promote Jay Leno’s forthcoming 10 p.m., five-night-a-week talk show kind of be taken as a dig at Conan O’Brien’s rocky-out-of-the-gates stewardship of The Tonight Show? Leno hasn’t been gone that long, really; it’s not like he’s a prizefighter coming out of retirement, or an actress coming back the small screen after a couple years of maternity leave. It’s just a weird song choice to me. Aimed at the segment of the old Tonight Show audience who wouldn’t know the Masturbating Bear from Comic the Insult Triumph Dog, the subtext seems to be, “Yeah, yeah… we know: but now you’ll get Jay earlier, and can go to bed at 11:10 after catching some local news, instead of 11:50, after his monologue!”
