Since its debut in 2002, "American Idol" has become a cultural institution. Its longevity is impressive but nowhere near the continuity of the Grand Ole Opry, which has held sway on Nashville radio since 1925.
Next week, the two all-American titles will join forces as "Idol" uses an Opry theme, requiring contestants to sing a song made famous by an Opry member. Tying it all together, current Opry stars Brad Paisley, Carrie Underwood and Randy Travis will perform on the show from Los Angeles’ Kodak Theatre on Wednesday.
