Arctic Monkeys insist they were happy when frontman Alex Turner launched his side project, The Last Shadow Puppets.
The singer created the group with The Rascals rocker Miles Kane and the pair achieved a U.K. number one album, The Age of the Understatement, last year (08).
Turner and Kane then decided to return to their prospective groups, and Kane has since left The Rascals to go solo.
And the other Arctic Monkeys rockers are adamant they did not mind Turner taking time out to write songs for another band.
Guitarist Jamie Cook says, "I felt like I was in a kinky open relationship. Which, strangely enough, I felt mostly okay about - I didn't begrudge him his fun with someone else."
But the bands delight at their London comeback show was short-lived - the power failed during their afterparty.
The British rockers played a hotly-anticipated show at the Brixton O2 Academy on Wednesday night (26Aug09), and later held a bash with celebrity guests including Australian singer Natalie Imbruglia.
But it turned into a shambles when the power cut out - forcing staff to serve food cold and use candles for light.
A source tells Britain's Daily Mirror newspaper, "The lads were on a high after their gig and wanted to celebrate. But a mass power cut thwarted their party plans.
"Organisers had to rush out for candles and serve the food cold. Chilled shepherd's pie may not be to everyone's liking but it went down a treat."
