Paul McCartney ’s previous New York-area performance took place three years ago at MetLife Stadium, capacity 82,500. His surprise show Tuesday night at the Bowery Ballroom fit, at most, 575.
It was probably less than that since McCartney’s sound board and gear — too much to fit backstage — occupied a portion of the floor space at the venerable downtown theater. The whole thing felt like, and was, a lark. McCartney announced the show just hours before taking the stage.
