Before Lady Gaga conquered the Fame Monster, she was a songwriter who pitched 'Telephone' to Britney Spears. This Auto-Tuned Britney demo is more bare-bones, but it holds up against Gaga's version anyway. Even before its authenticity was confirmed, any seasoned Britneyologist could tell it was our girl singing, with her distinctive vocal tics and barely repressed rage.

“Oh Sherrie”

Steve Perry's girlfriend Sherrie Swafford was actually in the studio when Perry began writing this song--his lone Top Ten hit as a solo act--with two co-writers. The trio began at midnight one night with just "Oh, Sherrie!" and "hold on, hold on." Three hours later, they had a complete song. Swafford, however, had to wait until the next day to hear it. "Sherrie actually got tired and went to bed," Perry said. She also appeared in the video, but their relationship did not hold on for long.
