It really happened: Perkins was there for a recording session with Lewis, who was the new kid. Presley and Cash came by separately, and soon an impromptu jam session happened. The show was nominated for three Tony Awards in 2010, including Best Musical, and now it’s at Cincinnati’s Aronoff Center for two weeks. Each character is featured in several of his best-known tunes — all in all, there’s “a whole lotta shakin’ goin’ on.” $28-$103. Tuesday-Sunday. Through March 3. Aronoff Center, 650 Walnut St., Downtown. 513-621-2787, cincinnatiarts.org.
