Sedond--nope, try again. It was this group's only song I ever heard played on the radio, but maybe someone from the Bay area around that time knew more of them. The song, which was one of those 10+ minute songs, was about a guy on a train in a tunnel that was going somewhere, he kept asking the conductor where they were headed, and the conductor just "walked on by"---finally, he gets to the motorman, who says I don't know, I'm just following the tracks. Typical 60s acid rock stuff.
Angela, since I'm usually just getting up then, I'm never listening, but I'll guess that it's Bruce Springstein's version of Santa Claus is Coming to Town?
