In January 1961, Dalida covered The Drifters' "Save the last dance for me" as "Garde Moi la Derniere Danse" that reached top two. It remained her biggest French hit of the year as she busied herself with another year-long world tour which started in Teheran on 18 February, in front of Iranian royal family in their Sa'dabad Palace. With a total of almost 200 dates, the tour's last leg included Dalida's first own concert residency at Olympia, premiering on 6 December. Due to her recent love affair, divorce from Morisse and new yé-yé wave, several critics announced it as "attestment of an end and downfall of Dalida". Indisputably, Dalida "brought the house down" according to Beuve-Méry of "Le Monde", as the month long show was a sell-out success with the premiere night broadcast live by Radio Europe N°1. Among other musical legends who attended, she was congratulated by Edith Piaf, who told her: "You are a winner, like me. After me, it will be you." Dalida also set the record for the biggest public attendance and the longest-running concert residency at the Olympia, with a total of 52,000 spectators in course of 30 days, that would be broken by herself in 1981. At the very end of the year, on 30 December Dalida completed her world tour in Olympia's Belgian equivalent Ancienne Belgique in Bruxelles.
