Tradition had that album, Bowling Green available on CD recently, part of a series of classic folk albums they had reissued at a budget price. I don't see it at CDNow, so I guess maybe it has been discontinued. Too bad. Many of the CD's in that series are available - look under the "Tradition" label at http://www.rykodisc.com
Oh - the Tradition site shows the CD is still available.
