From the website for dutch chazanus" chazzanut.com (Yes, they got to that name first!) There is a lot of information, links, and files to listen to there, but I am only posting one or two to give recognition to that site. Description from that site: "The Jewish Historical Museum in Amsterdam produced a unique CD with music from rare records of the pre-war choir of the Great Synagogue in Amsterdam conducted by Sam Englander. Unfortunately, this CD is currently out-of-print."
