Years in Jazz articles 

Hello! I see that you have recently spent some time expanding a variety of "Year In Jazz" articles, such as 1930 in Jazz and 1948 in Jazz. It appears that these edits have added orphaned references, which makes them show up on Category:Pages with broken reference names; a list of affected articles (about thirty) appears there. In some cases, the AnomieBOT has identified possible uses of the ref names from other pages, and while they appear to be the same, I don't know where content was copied from to fill out the "Year" articles. Could you revisit the articles, and make the appropriate changes? Thank you! -
