Gill, Harris On "Jay Leno" Before Country Music Hall Benefit

Vince Gill and Emmylou Harris continue to promote the Country Music Hall of Fame, this time on TV. The singers are slated to appear on NBC's "The Jay Leno Show" on Wednesday, in support of their upcoming "All for the Hall" benefit in Los Angeles. The special show is making its West Coast debut this year after 2007 and 2008 events in New York City. Gill and Harris, who were featured at last year's "All for the Hall" concert, lead a 2009 lineup that also includes Dwight Yoakam and Sheryl Crow. The "All for the Hall" concert, described as an old-fashioned "guitar pull" featuring songs, stories, and unique musical collaborations, will take place at the Club Nokia in L.A. on Thursday, the day after Gill and Harris visit "The Jay Leno Show."
