Search for "lolife" l o l i f e (two L's there). That was the name of his podcast. I used to have them somewhere. They were such great stories he told about those days. I'm not sure if they are on archive.org or not, or in iTunes. But worth a shot.

I recommend trying to contact him directly. https://lolife.com/ Based on the last paragraph there, it seems like he would be willing to respond (unless folks get weird.)

It's unlikely he pulled them down on his own. More likely either a cease and desist came, or they simply expired because it had been so long since they were posted. He may not even know that they aren't linkable any more.

Good luck!
