welcome, noodles

I've found the best way to search mudcat is to do a google site search - union songs site:mudcat.org, that way I can skim down & find the thread/s I want.

A great source of Australian union songs is occasional Mudcatter Mark Gregory's Union Songs He also includes songs from other countries,

world-wide links - Union Music and Cultural Sites - as Mark's site started in the 90s (like Mudcat) some of these could be dead.
