The iconic Kim Fowley, who co-wrote songs with Kiss and Alice Cooper, passed away yesterday at the age of 75. He’s known for his work with The Runaways, putting together Joan Jett and Lita Ford when they were just teenagers.

Fowley had been battling cancer in recent months, and was under the care of The Runaways vocalist Cherie Currie, who took him in when she heard of his condition.

Said Currie in September of last year:

“I love Kim. I really do. After everything I went through as a kid with him, I ended up becoming a mom and realized it was difficult for a man in his 30s to deal with five teenage girls. He’s a friend I admire who needed help, and I could be there for him.”

In a statement from E Street Band guitarist Steven Van Zandt, Fowley, “was working in the Underground Garage (Van Zandt’s Sirius XM radio show) until last week.”
