Oidreacht an Chláir doesn't seem to have any copies left but copies of the CD were available locally (ie the wider Miltown Malbay-Lahinch area)only a tour of the shops would be the way to see if there are any copies sitting around anywhere. You could try the Traditional Music Shop in Doolin, which is on-line and may or may not have a copy on the shelves.

The older tape will be long gone, Miltown library has two copies though.

I would note however someone remarking it would be a shame if Michael's playing would be remembered by what's on that CD.
