Fearlessly sharp, fabulously bonkers singer-songwriter Nellie McKay is a total original, which may be why her cover songs are so terrific. Her latest CD, My Weekly Reader, is a marvelous reinvention of tunes from the 1960s, including "Sunny Afternoon" and a perfect "Red Rubber Ball." McKay is also a passionate advocate for animal rights; this concert is a benefit for the Wild Bird Fund.
