Q I know that Willie Nelson's sister has always played piano in his band. Has she ever made any music of her own?
—Will Trabue, Tulare, Calif.
Bobbi Nelson, 76, sister to the singing and songwriting superstar, left a job demonstrating Hammond organs to play piano with her "baby" brother, who's now 74. That was 35 years ago, and she's been at Willie's musical side ever since. She branched out recently to record her solo debut, Audiobiography, a collection of piano versions of classic tunes including "Crazy," "Stardust" and "Down Yonder," and two new songs from Willie, who joins her vocally. "The only way for me to tell the story of my life," she says, "would be through music."
