The Guardian suggested of Kylie, "...her guest appearance works not because of her celebrity, but because she plays against it."
Here's the rest of the Guardian's writeup about Kylie:
"Rather than hogging the limelight, she slots herself perfectly into Scissor Sisters' world, gamely joining in with Shears and Ana Matronic's synchronised dance routines, providing an eerily accurate impersonation of the former's distinctive falsetto, dancing flirtatiously around guitarist Babydaddy. 'First time at Glastonbury baby!' yells Shears at her departing form when the song ends. In response, she flashes him a delighted look that suggests it won't be her last."
