I forgot to tell you all: Last Thursday I attended a gathering held by NARIP, the National Association of Record Industry Professionals ... and among the people I met was Rick Derringer's ex-wife, Elizabeth Derringer (she still uses the name). She runs a communications/PR firm and wanted to chat me up when she heard I do stuff for the Voice. But instead of talking shop, I asked her: "Is it true that 'Rikki Don't Lose That Number' was written with Rick in mind?" She replied that she's heard that but doesn't really know.
Just in case anyone ever wondered.
