I know there have been several threads about Glencoe, so here's whatcha do:
First, try the Digitrad. See the blue box at the top of this thread? Click on the letter of the first important word of a song title ("The" doesn't count), and follow your nose down to the title of the songs you're looking for.
If that doesn't work, try the Search and Supersearch filters in that box or at the top of the Forum. Type in the most important word of a title (remembering that there may be variations in spelling) and check the songs and threads that come up for you to look at.
If the version you hit in the Digitrad isn't the one you're looking for, don't forget to try the "Next Page" clicky thing -- sometimes it leads to the version you're after.
Then let us know if there are any you just can't locate.
