Their are two quartets that come to mind for the songs you mentioned:
Heehaw Quartet and Fairfield Four (I think). Granpa Jones was in both groups, and I think that the first one was the Fairfield Four. I'm sure that the second was heehaw Quartet. CDs are available for both.

There are many other collections of these available, in all kinds of formats. Put the songs you wanted into a search at Amazon, and see wjere they turn-up.

Another choice, depending on your taste, is the Chuckwagon gang.
Good Luck!!
