[artist id="13267"]Olivia Newton-John[/artist] is coming to Sue Sylvester's (Jane Lynch) rescue on Tuesday's (May 4) episode of "Glee." The episode will see the Australian pop singer/actress and the cheerleading coach remake the famous "Physical" video, after a video of Sue jazzercising is leaked.
"I totally geeked out when she started singing 'Physical,' " "Glee" musical producer Adam Anders told MTV News about the duet between Newton-John and Lynch. "I was like, 'What's happening?' She sounds exactly the same! But this is a whole new version of it. You'll be really surprised to hear it. It's not your mama's Olivia Newton-John."
Anders also promised that viewers will find the "Grease" star's appearance in the episode organic. "You can say what you want about it, but this show is real," he said. "At the heart of it, it's about real issues, real stories. When the music brings those stories out, it's really powerful."
Though Kristin Chenoweth and Idina Menzel have already graced the show this season, and Neil Patrick Harris has a guest appearance coming up, Anders maintains that the show's real star is the music. "The best part of 'Glee' is introducing new music to an older generation and old music to a newer generation. There's so much great music. We all listen to music in a vacuum, then we're exposed to things and love it. Olivia Newton-John is an example of that.
"It's a perfect marriage between the songs that were chosen and the storyline. When that happens, it moves people," he continued. "Music, at the end of the day, is all about emotion. When you get that reaction, people are gonna buy it."
