Although this solo-career retrospective ignores Robert Plant's fine first album (not to mention 1983's incandescent "In the Mood"), Sixty Six makes a convincing case that Plant's artistry didn't end with Led Zeppelin. Besides unveiling four pre-Zep rarities — including 1967 covers of "Hey Joe" and "For What It's Worth" — the set finds Plant's expressive voice in fine form on folk-rock hymns such as "Darkness, Darkness" or the "Kashmir" update "Calling to You." If only Plant could have gotten over his disdain for his early-Eighties work, Sixty Six would have been definitive.

“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.
