By the way, interesting bit about those two early German efforts, pre-MIDNIGHT EXPRESS. I think I sampled both of those and the SON OF MY FATHER album when I researched Moroder in 2015, but the album can’t have made much of an impact, because I didn’t seek it out to own.
The earliest Moroder album I own is EINZELGÄNGER from 1975 — a totally weird, experimental album. But then KNIGHTS IN WHITE SATIN the year after is more typical of the composer-producer-arranger. I do wonder if “I Wanna Funk With You Tonite” made some controversial waves at the time, due to the double entendre title.
