In a radio interview this morning with Phoenix station KISS, American Idol judge Paula Abdul revealed that next week’s performance-night theme will be Songs From the Year You Were Born. That means we’ll hear songs ranging from 1980 (Danny Gokey) to 1992 (Allison Iraheta), with a whole bunch of tunes from the 1984-86 period, when six of the nine remaining finalists were hatched. (If you click the above link to hear the interview, she spills the beans at the 12-minute mark.) A rep for the show says the theme will be officially announced during tonight’s results show.
