MMario: I've found dozens, maybe hundreds of songs at various places on the Internet by using Google and searching for a phrase from the song (in quotes) just as I did it in the experiment described above. But usually I don't restrict my search to Mudcat. (In this experiment, I restricted it by going to Google's "Advanced Search" page and putting "www.mudcat.org" in the "Domain" box.)

In fact, without the restriction, Google DOES find "way back in seventy three" but not at Mudcat. It finds it at http://sniff.numachi.com/~rickheit/dtrad/lookup.cgi?ti=ZACKMORM&tt=OSUSANNA, which is another site that hosts the Digital Tradition.

I don't really understand the meaning of all those parameters, but it shows that the Google spider somehow searches and indexes the lyrics at Yet Another Digital Tradition Page, but it doesn't index ours. And I don't see any obvious difference between the way their site is set up and the way Mudcat is set up. Can anyone explain the difference?
