It turns out that, in the wider scheme of things, (despite the former
appearing on DDR TV and the latter guest-starring in a TV drama) both
Donika Venkova and Margarita Goranova were never really absolutely
first-rank stars on the Bulgarian scene. There was another ‘Margarita’
(Hranova) who very much was, however….and guess what….she
performed a Bulgarian-language version of the Bee Gees’ ‘How Deep Is
Your Love?’ (well ‘BG’ does stand for Bulgaria!)
So, although it’s a ‘slowie’, I suppose that this amounts to ‘Bulgarian Disco’.
