Footage of Whitney Houston’s performance at Clive Davis’s Pre-Grammy party has surfaced. The diva applied her now raspy vocals to several classics in tribute to her cousin Dionne Warwick including ‘Walk On By’, ‘I Say A Little Prayer For You’ and ‘That’s What Friends Are For’.

Look below for all the action:
