I've NEVER heard this one and I find it hard to believe she was offered this role. The film verssion of Grease came out in 1978. Liza was just entering her thirties. Of course, Stockard Channing was, I believe, 35 or so when she (memorably) played Rizzo, so I guess this isn't that far-fetched. I am intrigued now as to what might have been!
