I hadn't logged into any of my accounts in a long time and discovered a lot of private messages asking for the audio clips from way back.
I've decided that it has been long enough that it wouldn't be unfair to the people who originally purchased these to just release them to the public. It took me a little time to find a private-enough service for file sharing.
All four clips are bundled into a ZIP file available from this location for the next 30 days:

Enjoy.
Thank you very much, it's been lovely to hear these after missing out on them the first time round :)
