This one or two compilation albums both definitely exist but they may or may not be the same one the first one was supposedly released on De-Lite in 1982 after "As One" (Jim Bonnefond is credited with production) but this is this LP that I read had track listings identical to "Spin Their Top Hits" (although the versions may be different) four years earlier which may be why it doesn't appear on the official website.
The second album does appear on the official website and is dated February, 1983 this is confusing me but as they both occur between "As One" and "In The Heart" they both go here.
Now continue to Twice As Kool: The Hits Of Kool & The Gang or In The Heart.
