The Hand me down copy I have is 386 MB. And I am on West Clare broadband (i.e. 0.1 Mb upload speed) so I am limited in what I can do, I am afraid.

Do you have the Leader lp where he tells stories and plays the tunes after?

The Gael Linn lp does come up every now and again, I got a good copy off ebay for a tenner a few years ago. Mind you, it took a bit of patience. The Collector EP also comes up, although a lot of the time now at silly prices.

I finally managed to get the scan up: Seamus Ennis story, cover No guarantee on how long it will stay there but you can get some information off it anyway.

I have a lot, and I mean a lot, of Ennis' music all sorts of informal recordings, archive material and whatnot.

You could try pipers.ie Na piobairi uilleann, there's a good bit of his playing in their online archive. I supplied a fair few recordings that were used for the book of his dance music.
