I want to second the recent recommendation of Roger Burgess's Carousel
Website both for its content and its audio-visual impact.  Roger, who in
real life is a State Department man living in Merrifield or Alexandria,
Va., started it a year or two ago, and it has since won several awards.
It keeps growing and expanding and now has several department of interest
to carousel people and band organ nuts, with wav files of Seabreeze band
organ tunes.
