Deletion of Henry Leck

Comment: it appears the nom has been asked to prove a negative.  5 sources are currently listed.  The first is self-referential as the organization founded by the subject, not otherwise notable.  The second may go towards establishing notability, hard to tell as the page has been deleted, and it may be a press release.  The rest are from his place of employment, which are not independent references.  They do not rise to the level of showing .  He is given a mention here http://books.google.com/books?id=ZEmLuBWeTPcC&pg=PA187&dq=%22Henry+Leck%22&hl=en&sa=X&ei=3wlhU7nkEMbI2gX9xoCoAQ&ved=0CEIQ6AEwBA#v=onepage&q=%22Henry%20Leck%22&f=false and here http://books.google.com/books?id=e09CNwAACAAJ&dq=%22Henry+Leck%22&hl=en&sa=X&ei=_wlhU6WFHqW22AXb2YCACQ&ved=0CFMQ6AEwBzgK (likely self-publilshed work).  This http://triblive.com/news/westmoreland/5916132-74/landman-chorus-festival#axzz30NeSvAkv also mentions him briefly, but would go much further towards establishing the notability of his choir.  He is a published composer arranger, with numerous publications by a major publisher http://www.halleonard.com/promo/promo.do?promotion=90137.  Through numerous passing mentions it is obvious his choirs have toured multiple times internationally, but these references provide no information on Leck the person
