Buckaroo and Buck's Polka were de rigeur for any lead flatpicker in Irish country bands in the '60's. And Buck was every bit Roy's equal, he just chose not do do it much on Hee-Haw, concentrating on the entertainment part of the show. Although there were a couple of bits where he sat and picked some hot lead guitar.
Boyoboy, he was a good'un, and he'll be missed.
