EDIT: this was playing on MuchMusic in Canada (Toronto) somewhere in 1982-84. Regrettably they do not have playlists from this period available (I tried!).
Video includes a single 20-something lead guitarist/vocalist. Long hair, cute, edgy voice with a bit of that Paulina Rubio power, only a deeper voice. I attach a simple piano version of the main melody --
Truly appreciate all the helpful suggestions on here! Thanks all.
Had a crazy flashback to this video. It's an upbeat rock song with a 20-something guitar girl. Lyrics all in Spanish. In one scene she is playing on railroad tracks. Can't recall much else. Was all over muchmusic in the early 80s. I already tried asking them for playlists :( no luck.
Want to get (and teach my daughter to play) the song.
