Based on the true story between a Texas housewife and one of country music’s brightest stars, “Always ... Patsy Cline” will make its annual appearance on the historic Holly Theater stage next week. The show is about Cline’s friendship with a fan from Houston named Louise Seger, who befriended the star in a Texas honky-tonk in 1961, and continued a correspondence with the singer until her death in 1963. The musical play, complete with down home country humor, true emotion and even some audience participation, includes many of Cline’s unforgettable hits such as “Crazy,” “I Fall to Pieces,” “Sweet Dreams” and “Walking After Midnight.”
