Why do top level late night talk show have low level bands?

Is it some kind of thing? Why is it always..."Tonight we have Mel Gibson....Cameron Diaz....LeBron James...and music by Streetcorner Joe and the Pan Handlers."

I don't know if all late night talk shows do this, but I've noticed it a lot on many different talk shows over the years. Why is the music never on par with the talent level of the interviews? They have A,B and C list stars with bottom of the bucket local cover bands??? WTF

I know I'm gonna get "they're underground bands" and "just because you've never heard of them doesn't mean nobody knows them or they're not good."

So if that's the case, why not interview some guy who nobody has ever heard of who wrote 1 book in 1975? Why? Because nobody wants to see him. Just like I don't want to see these no name bands that aren't good enough to be on the radio.

Viewership of late night talk/variety shows have dropped considerably over the last generation. Without a lot of viewers to watch the ads being run and inviting advertisers with more money the budget to pay a major nationally/internationally known performer and to fly them out to the studio simply isn't there.

So instead they are local cult bands that no one outside the city recording the show knows about or cares about. It costs less to pay a celebrity to sit and talk, than to pay one to stand up and perform.
