Found while surfing with a new search engine at this address (seems really nice!)A site which seems to have been created by a Choir singer from Wisconsin (in both German & English), but which has a VERY large database of American, French, German, Scots, Irish, English, Welsh, etc. songs, along with sections of Sea songs,Hymns, Christmas songs, and a special area for the songs of Fredrich Silcher...and an amazing number of all of these have nice midis!! Really worth the visit...(it says it has only been accessed a few thousand times in many months, so maybe it is not on most of our lists...)
I have put this in the links
