Helen Siff was the original Helga Helsenrott in, "Grandma Sylvia's Funeral." I would say I was her director but I have to admit she gave me some very good unsolicited tips. I will be forever grateful to her not only for her many contributions to the LA 99 seat theater production, but for committing to the project when it came to Off-Broadway. Having her there with me was a tremendous comfort and none of her eventual replacements every came close to her original comic inspiration. Thank you Helen. With love and very fond memories, Glenn Wein
