Linda Ronstadt and Hank Williams Jr.

In the first of two Poplar Creek shows, Linda Ronstadt played to an enthusiastic, predominantly adult audience, of many of whom sang along with the Mexican lyrics she belted out in her inimitable, guttoral soprano. I got the impression that if she needed to, she could do just as well without the microphone. The tour is in support of her latest album, “Canciones de Mi Padre” (Songs of My Father). Subtitled “A Romantic Evening in Old Mexico,” the Poplar Creek show was the same production that played for three weeks on Broadway. The two-act revue was as much theater as it was a concert.
