By Chris Carola, The Associated Press SARATOGA SPRINGS, N.Y. — Bob Dylan would surely still recognize the low-ceilinged room in Caffe Lena where he played a couple of gigs almost 60 years ago. But just about everything else about a venue that bills itself as the nation’s oldest continuously operating coffeehouse has undergone some major upgrades as part of a $2 million renovation project bankrolled in part by folk music performers themselves. Dylan performed twice there early in his career, when the young singer born in Minnesota as Robert Zimmerman was just making his way onto New York City’s folk scene.
