Johnson can be found on Girlschool's classic early '80s material: Demolition (1980), Hit and Run (1981), Screaming Blue Murder (1982) and Play Dirty (1983). She left Girlschool in 1984 but returned to the ranks in 1993 but exited the band once again in 2000 following the recordings of Not That Innocent: 21st Anniversary, released in 2002.
According to Wikipedia, the fact she had this disease was not widely known outside her close circle of friends and family. At Kelly’s memorial, her friend and former bandmate Tracey Lamb read the eulogy she had written for her:
“It doesn't shock or surprise me that there are so many of you here today for Kelly because Kelly touched all of our hearts with her love, friendship, her amazing persona and the way she inspired so many of us to take up or continue to play music. She was a true rock star, her agility on stage and when recording, her prolific song writing and strong delivery in every performance will always be remembered."
