Elizabeth Chan, 42, who writes and performs Christmas music, and pretty much only Christmas music — she has composed more than 1,200 songs — lives with her family in a two-bedroom rental in Battery Park City. Gathered around the Christmas tree with her are her husband, Andy Fraley, 45, a designer, and the couple’s children, Noelle, 5, who sometimes sings on Mom’s recordings, and Eva, 2.
