Best known for the novelty hit "Dead Skunk (in the Middle of the Road)," this veteran folk singer-songwriter has had a storied career that's even included a few acting gigs (he played the singing surgeon on M*A*S*H). A consummate storyteller, Wainwright is a singular American artist with more 20 albums to his credit. He returns to the Kent Stage tonight at 6:30 . Wesley Stace opens the show.
