See http://www.artistsofnote.com/michael/
looks like 2 concert cd's are coming out,
Also hoping that his wife, Barbara Barrow, is able to release the cd of her perfomance of Michael's concert version of Grapes of Wrath.
My favorite cover is the Gibson/Camp version of Spoon River.
Book Michael, as well as Steve, Cindy, and Anne, together or separate - they are great - check out the sounds through Steve's Compass Rose site.
Saw Liam Clancy at a book signing last year and he said The Dutchman was one of his favorite songs. We are very fortunate to have him in Chicago.
