We expect our rock stars to perform an encore, to play their biggest hits after doing the routine of walking off stage for a few minutes. But has that removed the surprise and feeling of the unexpected from our concerts? In the latest edition of Wordplay, the word of the day is “encore,” exploring the history of bands who did and didn’t perform one, and rock stars who have grown tired of the habit of doing a forced encore. It’s the curtain call for Cheap Trick, The Beatles, Father John Misty, Elvis and the School of Rock in this latest Wordplay.
