JC's Italian tunes
John Chambers' Italian tunes
The files here are mostly "full" pages with more than one version of each tune. If the file name includes "Song", it contains lyrics. If the file name includes "Tune", it's just the tune, usually in several keys, without lyrics.
I've been experimenting with a few tools to do useful things in directories full of .abc tune files:
Session lister - Collection lister - Tune lister
