Kate flexi-disc in magazine
A couple completely different blue Babooshka flexi-discs were issued in Russia. Some, like the one on the preceding page, include tracks by the Doobie Brothers. Others, like the one shown above, feature an additional Kate track, Fullhouse, and two songs by Ray Charles: Hit The Road Jack and I Can't Stop Loving You.
Different versions were distributed through magazines like the one shown above, and elsewhere. This particular copy of Krugozor contains a one-page article on Kate and six flexi-discs, one of which is the blue Babooshka. I don't know if any of them were actually (legally) authorized releases.
