Keith Moon's most serious relationship after his divorce from his wife Kim, was with Annette Walter-Lax. She was born in (approximately) 1956, making her ten years younger than Keith and a teenager when they began dating. I can't seem to find much information on Annette before she met Keith, so I'll just say she's Swedish, was born a brunette, and was a model when they met. Anyway, the two met in the summer of 1974, after a photographer asked Annette if she wanted to meet a "real drummer". Annette assumed that the meeting was a one-off, and didn't plan on seeing Keith again. However, while Annette was on a date with another man at a nightclub, she ran into Keith again. This time he was drunk and causing his usual mayhem in the club, but he took a minute to greet her. Annette and her date sat together at a table; shortly after she went to the bathroom. Her date was gone when she returned, and Keith had taken his place. The two were a couple by the end of that week, and shortly after began living together.
Annette wasn't much of a rock music fan, and had only heard of The Who in passing. So it came as a complete surprise when she realized that Keith was an alcoholic, and that everyday life with him involved a lot of booze and destruction. The same possessiveness Keith had displayed with Kim made a reappearance with Annette as well. He also forced Annette to give up her modeling career. Meanwhile, Keith continued bedding groupies, much to Annette's displeasure. At least he managed to hold off on the physical abuse this time around.
In 1975 Keith moved to Los Angeles and bought a house in Malibu; Annette went with him. They spent three turbulent years in California before returning to England. Once in London, the couple bought Harry Nilsson's flat at 12 Curzon Place. Around this time Keith began telling everyone that he and Annette were going to be married, but there was never any official engagement.
When Keith died in his sleep on September 7, 1978 Annette was the one to discover it. Understandably, she was distraught and inconsolable at Keith's untimely demise. She was heavily sedated during Keith's funeral service and reportedly collapsed at the Garden of Rememberance.
Eventually, though, Annette managed to "get over" Keith, so to speak. She began dating British television actor Gareth Hunt. They were married in the early '80s and had a son, Oliver, together. In 1981 Annette sold the story of hers and Keith's four- year relationship to a British tabloid. The Moon family was pissed about Annette's kissing-and-telling, but in Annette's own words "they made me an offer I couldn't refuse".
Nowadays Annette lives with her son in Stockholm, Sweden, divorced from her husband and without any permanent scars from her relationship with Keith.
