Needless to say, Den was around the 15th Street Lounge Studios a lot. I, on the other hand, was more like a fly-on-the-wall, around intermittently, during what were arguably/probably WRPI's most spectacular years. Then Den and I swaped places: He graduated and I started working at RPI, and have so, for the last 25+ years. Throughout this time I've been in, out, and about the station.
As of this "typing", all the audio clips are from the archive tapes, played back on the Ampex, onto DAT. I don't have RealAudio or .wav capability, but if you do, and are willing to do the conversion, I'll send you a tape. As space is no object at this time, I'll copy your files and attribute you the good deed.
