Context: Croxley Green is a large suburb of Rickmansworth and a civil parish in England with a population recorded at the 2011 Census of 12,562. Barry Aron Vann (born 1960) is an author, speaker and Chair of the Institute for Leadership Studies and professor of geography at University of the Cumberlands.  A prolific writer, Vann has published on a wide range of geographic topics.  He is most noted for his work in environmental perceptions and religious geography, in particular themes in which religious beliefs are associated with forming environmental perceptions and politicized regions such as Northern Ireland and the American Bible Belt.  Vann's work along the interface between religion and geography stresses the role of faith leaders in shaping the behaviors of others who in turn impact the cultural landscape.  An excellent description of how Vann conjoins geotheology and leadership, or the lack thereof, is expressed by Andrew Nicholls in The Journal of British Studies: “Vann acknowledges that the early Stuart policy of plantation facilitated the emigration of Scots to Ireland, and for those who feared and loathed the religious policies of the regime, early seventeenth century Ulster [nine northern counties in Ireland] could stand as a land of refuge.  But only for some.  Scotland featured numerous socioeconomic challenges, and for some dissenters, rising rents, unproductive lands, and failed crops were evidence of punishment from an angry God.  Therefore, migration became an opportunity to atone for one’s sins as well, although individuals leaving Scotland owing to poverty could expect little sympathy from their religious leaders.”  His book "Puritan Islam: The Geoexpansion of the Muslim World" was chosen as a Top 25 Outstanding Academic Title for 2012 by "Choice", a division of the American Library Association (ALA).  A review in the April 2012 issue of "Choice" referred to "Puritan Islam" as "perhaps the best geographical text produced on this subject since 2000" and of "utmost significance in finally taking the topic away from the emotional to where it needs to be--rational and explanatory discussion."  On her show "Spirited Debate", Lauren Green of Fox News called "Puritan Islam" a "fascinating book." Richard Woitach (born 1936) is an American conductor, pianist, and composer.  In 1959, after studying music at the Eastman School of Music, Woitach jointed the Metropolitan Opera in New York City and served as a staff conductor there until 1997.  In 1981, he collaborated with Canadian operatic soprano Teresa Stratas to record "The Unknown Kurt Weill", a landmark Nonesuch record that introduced unpublished songs of German composer Kurt Weill and for which Woitach received a Grammy nomination in 1982.  Woitach also was a long time collaborator with Canadian heldentenor Jon Vickers, where Woitach accompanied Vickers on the piano in several recorded recitals in both Canada and New York City.  Woitach lives with his wife soprano Jeryl Metz in the Upper West Side of New York City. Debra!
