BION, I saw a bagpipe wedding CD (I think) last week in the music department of the local Meijer superstore.
Searching Amazon will get you fast results for a CD, but let me also suggest, you can often find a live player that wouldn't cost too much. I would call the local police department's community relations desk. Same with the Fire Department. Those guys will know every piper in the county, which ones are good, and what they might charge.
