Saturday night is a tough one to call. Ray Davies on “Austin City Limits” – come on, it’s Ray Davies – or Vampire Weekend on SNL. Looks like our DVR is in for another workout.

A highlight of Monday’s schedule is an appearance by an artist who’s quickly becoming the hardest working man in show biz, Dave Stewart. His conversation with Tavis Smiley is guaranteed to be an interesting and entertaining one.
