Years ago, at Tanglewood, all the students were "given" brand new Baldwins to play. But in one hall, under the stage riggings, was an old, neglected, dirty, Mason & Hamlin A, probably from the 1910s or 20s. It never went unused as students conspired and competed for access to it. That was my favorite, if not the best. The best was its restored sibling, which I played a few years back at Cunningham in Philly.
