The Bangles: Eternal Flame

Susanna Hoffs confessed that she had recorded her lyrics for the Bangles' hit 'Eternal Flame' in a studio while completely naked, on the suggestion of her producer, Davitt Sigerson, who said that Olivia Newton-John gave her best recordings when she sang in the nude. He later admitted that it was a prank. Susanna had a screen in front of her though, so they couldn't see her in the control room, she had her privacy behind the screen, and wasn't on display.
