I only have one minor disagreemet with the earlier posts on this thread: I thought is was the singers rather than the songs that tended to get pickled.(:>) Only a teeny bit more seriously, how do we define "collector"? Is it only a person who puts the songs/tunes he/she has heard/learned in a book, or can it be a person who makes an audio or a/v recording of what they have learned, or can it even be the old codger in the corner of the pub who has a seemingly unlimited repetoire? Perhaps the issue is not that a song/tune is learned or "collected", but more one of how the "collection" is transmitted from one generation to another. Hmmm?
