TORONTO -- The French term for goodbye, "au revoir," translates loosely into English as "until we meet again." Which is, I guess, what Cher really meant the first time the 56-year-old dance-pop diva brought her Farewell Tour to the Air Canada Centre. That was back in mid-June when she actually launched her latest and final roadtrip after rehearsing in Toronto for a week at Maple Leaf Gardens. At the time, Toronto-area fans probably thought that was the last they'd ever see of her infamous Mohawk head-dress and glamorous Bob Mackie gowns in a live setting. But that retrospective show -- an hour and 45 minutes of non-stop spectacle, numerous costume changes and wigs, and hit after hit -- sold out in one day. And if you can sell out basically the same show again in the same market a mere five months later -- as Cher did last night at the ACC, albeit over a longer period of time -- why not return? "You guys are still as cool as you were last time!" the singer proclaimed after, once again, making her grand entrance, descending from the ceiling on top of a golden chandelier to the strain of U2's I Still Haven't Found What I'm Looking For. Her opening hair and outfit was the same, too -- a long blonde wig, a white fur-trimmed, diamond-encrusted, hooded coat -- before, that is, she stripped down to a navel-baring and beaded brown and silver costume for (This Is) A Song For The Lonely, the first single from her latest album, Living Proof. Other Mackie-designed ensembles making return engagements were a stunning turquoise and pink sari which she wore while riding a mechanical elephant (All Or Nothing, I Found Someone), the Mohawk-meets-Maori jumpsuit with the large black headdress (Bang Bang) and the fur vest with purple knit turtleneck and striped bellbottoms number (All I Really Want To Do, Half Breed, Gypsies, Tramps And Thieves, Dark Lady). Still, it felt like Cher -- who performed on an incredible stage dominated by two staircases, large amber-coloured lights, and three video screens -- had streamlined the show and made subtle changes to a few of the songs and outfits. Thankfully, though, she didn't get rid of her black leather jacket and barely-there black spandex body suit that exposed her backside tattoos during Strong Enough and If I Could Turn Back Time -- two of the standout songs of the night. Meanwhile, her seven-piece band and eight dancers/gymnasts, along with old clips from The Sonny & Cher Show that included performances with Tina Turner, Liberace, Elton John and David Bowie, filled in admirably whenever she left the stage to change into yet another costume. Also returning last night was '80s pop icon Cyndi Lauper as Cher's opening act. Decked out in a black tuxedo shirt, and matching pants with a red tartan train, the big-voiced 49-year-old performer enthusiastically took charge of the crowd, visiting often with fans in seats on the floor and at the side of the stage. Lauper's adorable son also sat in with his mother and her five-piece band for three songs, including her breakthrough hit Girls Just Wanna Have Fun, banging away intently on a mini-drum kit while wearing headphones.
