Well, Rose, didn't the link I provided lead you straight to the lyrics of the song? I just tried it, and it worked for me. Click here for the master search page of the International Lyrics Server. You'll note that there are many different ways to search. I often use the fulltext search function that's similar to the one we have here, and I search for a distinctive phrase from a song, rather than for the title. In this case, "milk of mercy" seemed to be a very distinctive phrase. Sure enough, it pulled up the right song on the first attempt. If I had done a title search like you did under "whiskey whiskey", I would have come up with nothing until I entered "Whiskey, Whiskey" punctuation and duplicate words can throw you off, since various search engines handle them differently. Words with varieties of spellings will throw you off, too - "whiskey" brings up too many songs, and "whisky" too few - both here and at the International Lyrics Server (here, though, you can enter whisk* and get the best of both worlds).
That same trick of searching for a distinctive phrase also works very well at my favorite Web search engine, http://hotbot.com/. Just make sure you set it for "exact phrase."
Other good places to search for lyrics are

Cowpie(Country)
Rabid Squirrel's Jazz Archive
LEO - Link Everything Online (UW Parkside & OLGA)
Lyrics World
International Lyrics Server

All of these links, by the way, are in our links section, along with lots of other gems. Hope that helps.
