Geoff
As you probably know most of my collection is on the BLSA website. There is mountains of stuff on there, all freely available without having to join anything.

Also there are some free tracks on the Mustrad website which could be accessed and linked to. You might need to ask Rod's permission but he'd be daft to refuse as it's all good publicity for his full album sales.

There are a few source singer tracks on our Yorkshire Garland website
yorkshirefolksong.net and there's someone on there called Geoff Lawes. Ever heard of him?
