Above, here's the second new "Tonight Show with Jay Leno" promo set to air on NBC. (You can watch the first one, which ran on Wednesday night, here.)
This one shows Leno on set -- from his primetime "Jay Leno Show." (He'll be using the same set for "Tonight," minus all those references to 10 p.m. that were on stage.)
Like the first promo, the Beatles' "Get Back" is used -- with the emphasis on the lyric, "Get back to where you once belonged."
It's NBC's way of subtly reminding everyone that this was Leno's time slot, and let's just kinda pretend that whole Leno/Conan kerfuffle never happened.
