You're welcome, Fergus.
I dare to say that there is none of us who hasn't asked at least once for a song that could have been found in the database with different search words. Dick reminds us often not to use names for a search, but if you do not know much more what else can you do? Entering "ball", for instance, also brings you this song (among more than onehundred nonhits).
But sometimes the square brackets indicating phrases and the star sign indicating indifference to spelling before or after a group of letters you are sure to be in a song help.
In your case, [lan* ball] or [bold O'Don*] would have done the job. However, this is written in hindsight. If for obscure reasons the DT-database would have these songs as "Brave O'Don*" and "Larrigan's ball" this approach would fail as well.
