On her new release, Dolly: Live in London, the Tennessee songbird proves that her voice is as big as her...uhm...hair. Maybe you've heard "Little Sparrow." Released in 2001, it is a haunting lament with roots in old time mountain music and maybe something older. (Musicologists, do I hear Celtic strains?) In this live version, she pares it to the essentials -- her voice, a dusting of backup vocals, and what I think is a steel guitar. Shedding the weight of other instruments, the song soars. It is delicate but grand like the monarch wings that have become Dolly's icon.
