Scene ... Last week, students at the Whitby School in Greenwich enrolled in Miss Z's School of Rock class were treated to a special live Skype call with Ron "Bumblefoot" Thal, a guitarist for Guns N' Roses. Thal answered students' questions and played his guitar. Students even treated "Bumblefoot" with a jam of their own. Guns N' Roses just completed a world tour and are on break before starting a 12-show "Appetite for Democracy" residency in Las Vegas.
