Help out a sick fella, wontcha?

Once upon a time back when Doctor Demento had an exclusive deal with XM Satellite Radio, I had pretty much unlimited access to voluminous amounts of archived Doctor Demento Radio Shows stretching all the way back in to the 1970's. Now they are all gone, and I can't find even a single one on all the internets :(

I don't suppose anybody could point me towards a good source, could they?
