Late night music, Jan. 26-30.

As a service to those who like to know what bands are playing on the five-nights-a-week late night talk shows, I've decided to offer a regular update. Make sure to set your TIVOs or DVRs if you don't stay up late enough to catch the performances on your own.

Monday, January 26: Ben Kweller

Tuesday, January 27: Andrew Bird

Thursday, January 29: No traditional musical guest but Graham Nash sits in with Paul Shaffer and the CBS Orchestra
