The eight remaining couples in Strictly Come Dancing 2011 have performed before a crowd of around 6000 as the show came live from London’s Wembley Arena on Saturday night.

And while Chelsee Healey once again triumphed at the top of the judges’ scoreboard, she was joined by The One Show’s Alex Jones, who headed the leader board for the first time this series.

Alex scored an impressive 35 out of 40 for her tango with James Jordan to the Frankie Goes To Hollywood hit Relax – performed on an evening which celebrated some of the biggest homegrown hits of the past few decades.

“You’ve taken to the tango so well,” Alesha Dixon told her, “it was atmospheric, dramatic and most importantly it was really believable.”

Bruno Tonioli, meanwhile, described the dance as “fascinating” and “stylish”, adding, “you got it absolutely right.”

Chelsee, meanwhile, received the same score for her samba with partner Pasha Kovalev, in which she paid tribute to the Spice Girls by dancing to Spice Up Your Life – and sporting a Union Jack printed dress.

However it was her dance moves which won praise – with Bruno describing the dance as “near perfect” and Len adding, “I don’t know about spice up your life, that for me spiced up my night.”

Jason Donovan and Harry Judd were just behind the leaders, each scoring 34 points out of 40 for their efforts.

Harry took to to the Wembley stage to perform a salsa with partner Aliona Vilani to the Elton John hit I’m Still Standing, while Jason and Kristina Rihanoff opted for an 80s themed jive to Wham’s Wake Me Up Before You Go Go.

Both routines won plaudits from the judges, with Len calling Harry’s salsa “full-on” and Alesha saying, “You had a natural feel to the dance, good job.”

However Jason was let down after performing a slight misstep towards the end of his routine, which did not go unnoticed.

“I suppose that would have been phenomenal if it wasn’t for that last movement,” Craig Revel Horwood said, while Bruno added, “It was magnificent, but the occasion overwhelmed you.”

Meanwhile Holly Valance was reunited with Artem Chigvintsev to perform her quickstep after the latter missed a week due to a back injury.

Alesha told her, “The quickstep really suits you,” but other judges weren’t so sure. “At times you’re thrilling,” Bruno said, “and at times you’re maddening.”

And Anita Dobson – who narrowly avoided elimination last weekend – was hoping her samba, to the classic 80s hit Come On Eileen, would be enough to escape the danger zone this time.

While Craig praised her for her “gorgeous rhythm” he was unsure about some of her moves, but Len spoke out in favour of the former EastEnders star. “You come out every dance and give it one hundred per cent,” he told her.

All of which left Robbie Savage and Russell Grant propping up the scoreboard, Robbie winning 26 points for his salsa with partner Ola Jordan, and Russell finishing in last place with 24 points for a jive with Flavia Cacace which began with him being “fired” out of a cannon.

“I know it’s Wembley but you treated this like the FA Cup Final,” Len told Robbie, “it was all a bit wild and savage unfortunately.”

However he did go on to describe it as “great entertainment” while Alesha added, “You opened the show like it was your own rock concert.”

Russell, meanwhile, thrilled the crowd – but the judges weren’t so sure about his dancing. Craig said of the routine, “Dumbo springs to mind,” but Len summed it up succinctly.

“I don’t care how many great dancers we have and how many series of Strictly we have,” he said, “people will always say ‘do you remember when Russell flew out of that cannon’?’

The results will be revealed on Sunday evening’s show.
