Oh yes, the Doris Day thing. Nah, it was just a silly lie Russell told the press. Because of this, many people believe the D. in Ron's name (Ronald D. Mael) stands for "Day" - however, it's "David".
I love the Halfnelson demos, by the way. Ron and Russ really hit the nail on the head in trying to recreate the "British invasion" sound - however, they were (and are) quite the anglophiles, having actually sold most of their possessions in order to be able to relocate to England in 1973-74. That, and they've just been known to create some interesting sounds that will, and have never been, familiar to America. ;D
