The house lights had come on and the 7,000-strong audience were starting to make their way out of the Singapore Indoor Stadium after a 3 1/2 hour long concert by K-pop mega group Super Junior.But suddenly, Eunhyuk, one of the group's eight members, made a surprise return onstage alone to speak out for his fellow performers Henry Lau and Zhou Mi, reports an article in The Straits Times Communities.The two are part of Super Junior M, a spin-off from the Super Junior main group of 13 members (only eight are active now), targeted at the Mandopop fanbase.The sub-group have been embroiled in controversy since their inception in 2007, as zealous Super Junior fans created the Only 13 petition, calling out to SM Entertainment, which manages Super Junior, to denounce the group.Onstage, Eunhyuk appealed to fans to support Henry and Zhoumi. He reaffirmed that they are not members of the main Super Junior group, but are still part of the Super Junior family."Doing Super Shows with them, watching them wait for hours in the waiting room after performing only three or four songs made us sad," he said in Korean.This show of brotherhood was evident throughout the concert where Henry and Zhoumi shared the stage with the eight main stays - Eunhyuk, Kangin, Siwon, Ryeowook, Shindong, Sungmin,, Donghae and Kyuhyun.Unlike in previous Super Junior concerts, the group's dance moves lacked their usual trademark precision timing, especially in fast numbers such as their hit song, Sorry, Sorry.SuperShow 5 also focused more on team pairings rather than individual showcases. Shindong, despite his girth, and Eunhyuk, with his six-pack abs, delivered a high-energy dance sequence. Ryeowook, Kyuhyun, Zhoumi and Sungmin showed off their singing prowess with a rendition of Michael Bolton's How Am I Supposed To Live Without You.One of the funniest segments had to be when Siwon, Ryeowook, Kangin and Sungmin sand and danced in drag. The show-stealer was Kangin who, wearing a blonde wig and a red top, revealed his midriff while posing sexily on the floor.Photos: Zinkie AwFor more photos from the concert, view the gallery below.
