Little Richard and Yoko Ono, though few on rock's current A-list, made it to the ribbon-cutting ceremony today in Cleveland for the $92 million Rock and Roll Hall of Fame, a six-story glass and steel pyramid that may actually be worth the investment. "It's a very important museum," says music critic Christopher John Farley. "It is a lot more than seeing Bruce Springsteen's junior college poetry. It documents the history of an American art form. It's a great looking building that really captures the spirit of the music." The museum opens Saturday.
