George Michael and Andrew Ridgeley are set to reform Wham! for a "one-off pop extravaganza", their first live show in 24 years, to mark the 30th anniversary of the band's first hit 'Wham Rap'.

Wham! split up in 1986 when Michael became disillusioned with the band and wanted to create music aimed at a more sophisticated audience, leading to a successful career as a solo musician. Ridgeley, meanwhile, attempted everything from acting to motor racing but failed to achieve any significant success.

The Daily Mirror is quoting a source as saying: "George and Andrew have often said that their Club Tropicana days are behind them. But seeing as their anniversary coincides with George releasing new material, it's one of those 'now or never moments'".

"They probably won't do a long tour or release new material like Take That but they do want to commemorate the event with a big gig... and an even bigger party!"

The source continued: "A reunion had been planned in 2006 at George's Wembley concert but Andrew was said to have been 'too sick with nerves' to join him on stage."

Ridgeley currently lives in Cornwall with his wife, Bananarama star Keren Woodward, while Michael is set to resume touring after the summer after a life-threatening bout of pneumonia.
