Seems to me that Guest Peg wants to know how to find the Music for the songs she has found here. Here is the SuperSearch result for and @mermaid:
Mermaid. If there is a Click to play link at the bottom of the page, the sheet music can be found here:
DT Mirror.
This site seems to be down at the moment, but keep trying.Also, many of the songs posted in the forum have either a MIDI or an ABC tune attached. To learn about ABC, look for Chris Walshaw's ABC Home page. It's a great tool.
