Barry Manilow and Rosie Rodriguez

Rosie Rodriguez, a lifelong Barry Manilow fan, never saw it coming. In 2004, she went to a Chicago restaurant to tell Oprah Show producers why she's Barry's biggest fan. In the midst of her phony interview, she mentioned her favorite song, "Can't Smile Without You."

Without missing a beat, Barry sneaked in behind Rosie and began playing his hit on the restaurant's piano. "Oh my God," Rosie said. "This is so him!"

After that show, Rosie attended her first Barry Manilow concert in Las Vegas. Now, she says her favorite song is "Weekend in New England."
