When Yeas & Nays interviewed Lifehouse frontman Jason Wade last week, he admitted that the band was full of foodies. So it’s not surprising that the band popped into Mike Isabella’s Graffiato Sunday night, posing for pictures with the “Top Chef” contestant. The group’s new album was being piped throughout the restaurant. Most of the patrons didn’t recognize the band, best known for its 2001 hit “Hanging by a Moment.”
