Originally by Karyn White in the late 80's, Superwoman is a song which has sung by many. I found this cover by a group call "High Vocality" in iTunes, within just seconds i've fall in love to it. Can't find them any other place in YouTube or Spotify, hence the group name "High Vocality". I presume they are individual singers now, like "Angela Mink". Try this track sample, get it over iTunes Store :)
