Although I'd characterize the sound as ok rather than especially good, I'll nevertheless mention The New Christy Minstrels "Greatest Hits" CD. Very likable music, IMO, including their best known hits from the 1960's such as "Today" and "Green, Green."
Regarding the comments about lack of follow-up by the OP, I'm not sure that everyone has noticed that his post was from 2005.
