Deletion of Cashbox Top 100 number-one singles of 1965

Comment: These are notable charts: even ''Billboard (magazine)|Billboard'' notes ''Cash Box'', in the same breath as its own charts, as a key part of music charting history (Michaelangelo Matos. "Counting 'Em Down Through The Years", ''Billboard'' Sep. 20, 2008; '''120''' (38): 34). A distinction needs to be made between "not currently verified" and "unverifiable"—it's the latter one that is a reason for deletion according to |policy. Presumably all these charts can be verified using reliable sources: books like http://books.google.ca/books?id=9O4ZAQAAIAAJ&dq=%22cash+box%22+charts&hl=en&ei=Wku-TKOPN4nAnAeW_dGJDg&sa=X&oi=book_result&ct=result&resnum=1&ved=0CDEQ6AEwAA this one, or the original print magazines themselves. So it's an editing question rather than a deletion one
