Each tune page features a chord chart for the tune. The title usually links to a page in http://music.gordfisch.net/montrealsession which has the sheet music, ABC version of the tune and a link to a midi file where you can listen to the tune.
Also, some pages have links to recordings by me playing the tunes and/or links to others on YouTube performing the tunes. For any tune, a quick search on youtube usually leads to a few versions by different players.
