Lyrics:

O Isis and Osiris favor
this noble pair with wisdom's light! 
Grant them your aid in their endeavor.
Lead them to find the path of right.
Lead them to find the path of right.

Let them be strong against temptation.
But if they fail in their probation
Do not their virtue need deny.
Take them to your abode on high.
Take them to your abode on high.

Masonic Music - Haydn and Mozart

Well, the title is a bit misleading. It's just music by the composers, who were both Freemasons, but not necessarily Masonic in nature. I found this on Bro. Chris Hodapp's blog, which he gives credit to a Mark Haworth, so I have absolutely zero credit in finding this, just wanted to add it to my blog. All credit is due to the aforementioned.

Here is the playlist Bro. Hodapp linked.

And, provided you have RealPlayer (blegh), here is the audio file itself.
