Whoa! Thanks to marek for this one!
"It's early and unknown recording called "Obłęd w podmiejskiej dyskotece" (Insanity In The Suburban Disco / Madness In The Out-of-town Disco) from "Historie nieznane 1971-1991" (Unknown Stories 1971-1991) album. It was recorded when Basia was singing with Perfect band."
No one will ever claim this as part of Basia canon but it's neat to see something like this surface.
