Ron Yost mentions Brian Steptoe's web page with understandable enthusiasm.
Brian is a professional photographer with a special interest in British
merry-go-rounds and fairground organs.  Brian and his wife, Jean, have
even come over to the U.S. for the last two annual National Carousel
Association conventions.  Both are wonderful people.  Brian has published
a book on gallopers and also sells several good cassette recordings of
British fairground organs.
