Forget about all the studio-thrown premiere after-parties at prior Cannes, from Paramount’s Rocketman with Elton John performing at the beach, and Warner Bros’ Elvis which touted a King of Rock Roll drone show. amfAR‘s annual gala, this year counting 30 years, blew them all away, capped off early Friday AM by a mind-blowing mini-concert by Cher who got the crowd on its feet after a four-hour auction with such hits as “Believe” and “If I Could Turn Back Time” and covers of Abba’s “Waterloo” and Marc Cohn’s “Walking in Memphis”. Vocally and in regards to sheer stage dynamic, Cher, at 78, is a force to be reckoned with; delivering a truly unforgettable pitch-perfect performance.
