box set has 9 CD's and is chock full of Ray's versions of classic novelty and comedy songs of the last 60+ years.
Edit 3-21-2012: Here's Ray's interview with Michael Horn of CRN from March 19th. I wasn't able to access the link yesterday because my flash player needed updated. It's since been updated and here's the link to Ray's interview. Several of Ray's own recordings, in their entirety, are played at various times in the interview.
