On the Scent of " Scent of a Woman."

Nicola Beneditti is a Scot of Italian descent whose looks remind you of Sophia Loren and whose violin music sounds like strains coming from heaven.  I had never heard of her until 2014 when my wife cajoled me to going to a concert she was giving at he Kennedy Center. Smitten by her artistry, I immediately bought her three most recent CDs.
The best one is called "The Silver Violin." In Britain, it was a top selling record, besting all of the charts. She plays movie themes as well as fine classical works- some by Corngold are particularly lovely.
  She also plays "Scent of a Woman." Remember the movie with Al Pacino.  I wanted to know who composed the piece of tango and discovered through Wikipedia that it was written by two South Americans in 1935-both killed in a plane crash shortly after its release.  They were Carlos Gardel and Alfredo La Pera.   The song's original title was Pa Una Cabeza, which means "by a head," alluding to horse racing. I urge you to read Gardel's Wikipedia bio. He was an amazing entertainer, quite poular in the US as he was in South America:
