I was just watching a movie "Small Town Girl " 1936. I wasn't really paying attention and then one of the characters said, ,,,,,,,,,,,,,, "...............Stairway to Paradise" this really percked up my ears and watching the movie a little longer a character was introduced as "ZOSO" "Zoso" this and "Zoso"
could this classic film have been a partial inspiration? I guess we'll never know for sure.
