What gospel group's version of Tom Wait's "Way Down in the Hole" was used for the first season of The Wire?

 Answer: (Blind Boys of Alabama) Tom Waits wrote and recorded "Way Down in the Hole" back in 1987, but it has become best known as the theme for the TV series, "The Wire". Each season has featured a different version of the song. In the first season, it was performed by the Blind Boys of Alabama and in the second season by Tom Waits himself. Season three featured the Neville Brothers, season four a specially-recorded version by some Baltimore teenagers and season five features the singing of Steve Earle.
