There are two other guests scheduled, with Pete designated as the "musical guest."

If the usual format holds, that might mean that Pete will appear only in the final five minutes, performing ~ but not sit next to the desk for an interview/conversation earlier in the show. (Two interviewees plus a musical act is the usual lineup.)

When a guest who is deemed "interview-worthy" is also a musician who performs in the fianl musical segment, there is sually only one other guest scheduled. However, there are occasional exceptions. I sure hope Pete gets to talk, at least a little bit.
