That's a good yarn EBarnacle.

Bob - I saw Bob Zentz play here in Wellington, NZ last year (concert of the year) and remember that song.

I was thinking that a crucial factor in the bagpipe story was that it was a whole squad of bagpipers playing, generating a substantial volume I imagine, that attracted the pod of whales. I'm not sure how sensitive hearing whales have, but it seems that they would require a 'sound system' of their own proportions to get really interested.
