In 1997 and 1998 Lockett felt his health taking a bad direction. He intermittently suffered from what he shrugged off as "a cold" or "the flu," always maintaining that whatever was nagging him was unrelated to the HIV. His artmaking became paralyzed by his gloom. During his final two years he was briefly artistically invigorated by the death of Princess Diana, in whose honor he made a series of valedictory, quilt-like works.
