Seems I posted some wrong links, and probably discouraged a few people -- 49 or so.

Here are the real links, same as the ones now listed in "Comparison"

Trip-Toe Thru the Few Blips
http://www.sibeliusmusic.com/mp3/6/7/5/67551.mp3

Trip-Toe Prelude and Fugue
http://www.sibeliusmusic.com/mp3/6/7/5/67554.mp3

Thanks to Larry Alexander for drawing my attention to the stupid error.
