My fav is a tune called "Foggy Mountain Breakdown" written by the late great Earl Scruggs. It was the theme song to the 1960's movie "Bonnie & Clyde" starring Faye Dunaway and Warren Beaty.
and the other is "cavatina" from the 1978 movie, "the deer hunter" with Robert Dinero"
I like this rendition best . .
