What teen queen is often called the reincarnation of Patsy Cline?

LeAnn Rimes

In 1996, LeAnn Rimes burst out of nowhere with her debut single, "Blue," which immediately captured the attention of country fans across America. It wasn't just the fact that her rich, powerful vocals were remarkably similar to Patsy Cline — it was the fact that Rimes was only 13 years old.

There's an interesting urban (or perhaps I should say "country") legend that the song "Blue" was originally written for Patsy Cline and shelved after her death, because no other singer wanted to touch it.

I almost posted a question on this last year, until I researched it a bit more and discovered that the whole tale seems to have been a publicity stunt, intended to promote Rimes as Cline's "heir."

There will never be another Patsy Cline.
