The host with the most. Well, the host with the microphone tonight. Dave Grohl makes his return to late night TV this Halloween. Filling in for Jimmy Kimmel as his son prepares for heart surgery. Dave Grohl is as comfortable in front of a camera as he is on stage at Wembley Stadium. Tonight’s treat? Alice Cooper. He’ll be Dave’s guest and coincidentally, performing.  So take the kids out for candy then bundle up on the couch and catch Jimmy Kimmel Live starting at 10:35 central on ABC.
