Olivia Newton-John almost didn't release mega-hit "Physical"

In a recent interview for AOL/Spinner.com, Olivia Newton-John talks about the anniversary of her mega-hit "Physical" and how she almost didn't release the song.

"I had a bit of a panic session," she tells Spinner. "I went, 'Oh my God! I can't put this out. It's way too radical! What are people going to think of me?' I said to my manager, 'You've got to pull it. It's too cheeky.' And he said, 'It's too late, it's gone to radio.' Of course, it went to No. 1 in like four weeks. I've learned to live with it."

'Physical' became Newton-John's biggest hit single in the U.S., where it topped the Billboard charts on Nov. 21, 1981, and stayed there for a total of 10 weeks. The song was accompanied by a music video featuring a headband-wearing Newton-John and a group of muscular and overweight men exercising in a gym.

"It seems like a long time ago," Newton-John says now about recording the song, "but it also seems like no time ago. It's really interesting -- just recently, I got a call from Brian Grant, who was the director of the [video]. They're doing a life story on him and I haven't seen him since we did the video. And then I did it again on 'Glee.' They recreated the whole set. It's sort of following me around again."
