Why have'nt they released HSCPT1 yet?

[pesto pizza]

The Beasties were always gonna release a part 1 & 2 of Hot sauce committee, so why have'nt we had the other part yet?
Its not "new" recordings or did they really loose their only copy of the another part down south in that zip lock sports bag?
Or is the other part one big joke like the fake samples on HSCPT2 because if it is, its worked on me for 10 years!
