Gavin made some Christian movies before he died. The Secret of Johnathan Speer is a tear jerker. I have given used copies of the DVD to friends in addiction recovery that don't attend church and it moves them.
I hadn't heard of Cindy Williams' death. I used to watch the reruns of Laverne & Shirley everyday after school when I was a kid. It was a big deal when they moved from Milwaukee to Hollywood.
