Query: Johnny Winter's Killer Rock and Roll medley

I was looking for a CD version of a cassette tape of a Johnny and Edgar Winter live concert, which I've misplaced.There's a killer medly of old rock and roll hits I was particularly hoping to find. This CD isn't the one. I've since discovered the one I want is a collector's item and is priced out of my range. I'll keep looking in the attic for the cassette version.
