Seattle Music: 'Minus Five' Scott McCaughey is a fixture on Seattle's music scene. The co-founder of the Young Fresh Fellows has never quite achieved the success other Seattle musicians enjoyed, but he gets by as the unofficial fifth member of REM. For years, he's had his own unofficial band called The Minus Five. Unofficial band-mates on a new CD include REM's Peter Buck and Wilco's Jeff Tweedy. Marcie Sillman reports.
