Hi again (from Scotland!) Lin - I checked with Barbara and she is ok for me to share her email(which is how l bought mine):
barbarawright22@googlemail.com

(I told her you were in USA so she can check postage cost)
If you email her she can let you know what cds and dvds are available. I believe they are now all at reduced prices..... don't hang about in case others have read this post!!)

You can also google John Wright Band (if you do his name alone there are too many!!) to have a look at him, the band, history, albums, memorial concert etc.

It is also worth checking youtube?
And a general internet search will take you to other providers of albums eg greentrax (not necessarily at reduced prices, tho maybe there will be some Barbara does not have?)
