Ah...is there a Mazurka that follows it in your set? I'd be interested...we usually segue into a song...a Christy Moore number called Ride On...
It's on Anglo international, CD 1; the playlist says "Petit Valse," which is a very pretty French waltz we play, and just "Mazurka," which is basically the same tune as Crested Hen. A very nice combination that dancers seem to like.
Thanks for the other suggestions. I am all-too-familiar with the problem of poor abc files, but the combination of abc and internet archives still represent a fantastic resource.
Another scource for waltzes for dancing is from Vivian Williams at www.VoyagerRecords.com. She has a nice CD of 25 waltzes with accompanying sheet music.
Would the waltz you are playing be Glenn Echo?
