The Monthly Song List is posted starting at the beginning of the month, and completes by the end of that month. It remains on the site through the month following its posting. So, the January list remains through the end of February, February through the end of March, and so on. The current lists can be found on this page. If you are trying to find a monthly list outside of those parameters, it won't be on the site. If there is a specific song that you desire, Email the webmaster of the site with your request and will see what can be done.
Tips for searching: This is a keyword type search. It works best when searching for a single word rather than a complex phrase. To search for Jolson movies, type "movie," for a song, type the title. Spelling counts, and exact phrasing counts as well. So, searching for "something about Jolson's death" will find nothing, whereas "death" is more likely to produce a result. In this type of search engine, less is more!
