Heard another interesting tape last night.
On the first side was Boston's album "Don't Look Back." After the end of the album, there were some recordings of CKFM doing the top 900 songs of all time.
Side B featured the AC/DC album "Let There Be Rock" with more of the countdown featured afterwords. A Simply Red song was introduced as song #412.
An unidentified male and female were featured separately. I have no idea what year the CKFM airchecks were from. The woman said "going back to 1988" for the Simply Red song, but the two albums are from over 10 years before that.
