Whenever someone from our chatper gets lavaleered, pinned, or married, upon the brother's request, we will sing one of our songs(Sigma Nu Girl, which can be found on the "Sing Sigma Nu cd, and as well as in our chapter's song files). It's a tasteful, and rather nice song, though how they sing it may not be as pretty!
Congrats, and Good Luck. I'm sure they will do something nice, rather than something tasteless.
