I know from having been my collegiate chapter's music chair that TriSigma has both a songbook (with lyrics and sheet music) as well as a CD of the songs. I'd hazard a guess that we're not the only NPC sorority to do so. It'd be worth a shot contacting your Nat'l/Int'l HQ to see if Zeta or TriDelta did something along those lines. Good luck!
