For myself, I find the "Digitrad and Forum Search" on the main Forum page to be the most useful of the search engines available on this site, as it searches the bodies of files in the DT database and Forum discussions as well as their titles; in this case, a search for the title of either song would have found not only song texts, but also discussions and background information.  More information about the Mudcat and finding your way around it is available in the FAQ thread at the top of the thread list; I strongly recommend that you read through it.
