A 100-year-old woman from Twin Falls will appear on The Tonight Show with Jay Leno tonight, and she can't wait to meet Jay. Dorothy Custer was named the "Pioneer of the Year" and played her harmonica for Idaho's News Channel 7's Larry Gebert. Now, she'll play it for Jay Leno and in front of a national TV audience. Custer told Gebert that one of her goals in life was to live longer then her 94 year old grandmother.  She plans to play "In the Good Ole Summertime" and said she'd love to sing for Jay too. Custer said she loves Jay Leno and has been watching him for years.
