Ann and Nancy Wilson decided to usher in the holidays by reaching out to vocalists they sincerely admired (and had always wanted to work with). The result is "Please Come Home for Christmas," a bluesy holiday love song sung by Ann Wilson and Aaron Neville; and "All Through the Night," a new take on the Welsh folk carol sung by Nancy Wilson with background vocal support by Richard Marx. Both tracks were produced by 19-time Grammy Award winning musician and producer Emilio Estefan.
