a few notes about this search page:
when using "and" as the search method for all three song fields, the search uses a technique called recursion whereby each builds upon the results of the previous one. in other words, the second song will be searched for in the results of the first song search. the third song will then be searched for within the results of the first two.
keeping this in mind, changing the search methods provides a variety of different combinations and results.
if the first song field is left blank, the rest of the song searching choices are ignored. so, leave it blank if you only want to search on venue information, for example.
