Thanks.
I didn't use your script, but I was able to unzip all but one of the files.
File 3029, of the 4282 files, had unrecoverable errors.
All the others were turned into:
rec0nnnncarols051011x.tbz
I concatenated these into file xxx.tar and ran a extract.
It worked, mostly. But it died at the place where there was a missing
piece. I think I need some kind of filler that allows tar to get
past the glitch and keep going. Or maybe I just have to be
satisfied with only 3/4 recovery. 

Are there any known approaches that recover the data following the
bad spot?
