Hi, do you mean program notes for the piece or merely the sheet music? Since this is a very famous piece, a quick google search on the piece will yield quite a bit of analysis of the piece already. You could also try including the opus number, Op.18, to get more results if necessary. If its the sheet music, check on http://imslp.org/wiki/Main_Page. It's an awesome database of public domain sheet music. Direct link to the sheet music: http://imslp.info/files/imglnks/usimg/8/81/IMSLP00496-Chopin_-_Grand_Waltz__Op_18.pdf Hope this helps!
