The Sunday night headliner at Bonnaroo is usually greeted with dwindling crowds as festivalgoers rush to beat the traffic. Not Elton John, as it seemed like half of Tennessee packed onto the lawn to watch the Rock and Roll Hall of Famer close out the 2014 Bonnaroo. Even though some of the songs were four decades old, Elton managed to breathe new life into them, either through new arrangements or different approaches or extended codas. Take "Rocket Man" for example: Thanks to a jazzier, almost-Shatner-esque intro and an outro that soared to an interstellar climax, hearing "Rocket Man" at Bonnaroo wasn't the same as hearing "Rocket Man" on the radio. In many ways, it was better. Elton's set did feature one surprise: Ben Folds — in town for the Superjam — guested on "Grey Seal." In the performance's most tender moment, Elton dedicated "Don't Let the Sun Go Down on Me" to Casey Kasem, who passed away earlier in the day.
