Old thread, but whenever I search for "Crazy Irving", this is one of the rare and only prominent results. I was about 7 years old when I went on the address on City Councillors Street. According to some 800kb disks from the era that I still have (and they still work on my original machine), the address was 1440 City Councillors Street. I've attached a pic of them, as well as what you could see from Google Street last year or so.
I have very fond memories of that place - always trying the newest games I could. I was always hungry for more games for our Mac Plus, but I also remember checking out the Amiga in its early days and being just floored by the fluid 3d animations it could churn out.
One of the many softwares we got from that place was Studio Session, a music composer that allowed 6 tracks of sampled digitized instruments, allowing for surprisingly rich music in glorious 11 kHz. Inside our 3 diskette bundle, there were some crude unfinished transcriptions of some Led Zeppelin songs (Black Dog, Dazed and Confused, etc). There were very partial, often only had 1 track to them. It felt like the beginning of some random client's doodling with the program (or maybe it was some employee's tests with it) - in any case, it was part of the stuff that we got.
If you want to check out Studio Session, I recorded them from an emulator:
if anyone ever reads this and is interested, I could also record these partial Led Zep songs as well!
