Is there a version of the AC DC album Back in Black that is music only
- with ZERO vocals - just an instrumental version?

I post it as a comment because I am not sure if this answer your
question:
There is a CD named "Jam With AC/DC":
"Description:
Learn 8 of AC/DCs songs note for note and then jam with a professional
session band. Includes Let There Be Rock, Back In Black, For Those
About To Rock, Whole Lotta Rosie and Highway To Hell. With full lyrics
and vocal lines.
Format: Instrumental Album   Length: 96pp   Language: English."

Please let me know if this is the CD that you are looking for and I
will post this as answer.
If not also let me know and I will continue the research.

Regards.

no that's not it.  The problem is the answer may be there is no such
CD.  My goal is to find this and other CDs without the lyric track by
the original artists - not session folks or karaoke-type tapes or CDs.
