Romy Haag sings "Everybody Knows"

Every time I watch "American Horror Story: Freakshow," I can't help but think that Jessica Lange's character is inspired by Romy Haag, the transsexual cabaret singer and actress who served as David Bowie's muse in the '70s.  Here she is covering Leonard Cohen's "Everybody Knows" in 2010 in German and English.  Am I imagining things?
