For you glittering urbanites in the Big Apple, news reaches me that Maggie, Terre, and Suzzi Roche will sing together for the first time in three and a half years on the seventh of December, at Battery Park in Manhattan (said to be "way, way down, near the Bowery"). Thing starts at 5:45.Those of us for whom these sisters'lovely voices locking together on a chord is one of the reasons the earth is good are happy about this.
