"That is a mother's grief, you know, because Whitney died at that hotel... All that it meant was that her... continuing pain was such that she could not attend a party, even if we were tributing (sic) Whitney, but of course it was the polite thing to do as we invited her brother and sister-in-law. We invited Cissy, but I understood." Music mogul Clive Davis fully understands why Whitney Houston's mum Cissy called his invitation for her to attend his Grammy Awards eve party "obscene". The bash was held at the same hotel where her daughter died a year ago (Feb12).
