Q: Also, what happens after they say they have to take a commercial break? The show isn't live, so do they just keep carrying on with the interview right away?
A: the band starts a song, they go to commercial, dave takes off his coat and paces around nervously, maybe chats a bit with bill sheft about show details, the band is playing the entire time. usually it's only about 60 seconds, and then the 5 second hand count from the director and it's back on and the band finds an end to the song wherever they are. the break can be any length, depending on if there is anything that needs to be done, but it is usually shorter than a TV commercial break, and often can be as short as 30 seconds if there's nothing that needs to be done
